NC****	Identifier for messages from the netCDF library

Message identifier	Error message	Explanation
PA0001	manual restart settings requires file activation string "restart"	Values for parameters dt_restart or/and restart_time have been given in the &runtime_parameters-NAMELIST. This also requires to give the file activation string "restart" with palmbuild-option -a, because otherwise the restart files wouldn't be generated at the end of the PALM run. Repeat the run with -a ".... restart" or remove parameters dt_restart or/and restart_time from your NAMELIST-file.
PA0002	3rd dimension of array "XXX" is larger than number of domain height levels: [size_of_3rd_dimension of XXX] > [nz+1]. Reading from file via MPI-IO not possible.	This is an internal error. If you did not add any user code to your simulation, please report this error via the trouble-ticket system. If you added user code and you try to read a 3-D variable from the restart files using the restart_data_mpi_io_mod module, the array you try to read is too large. It must not contain more entries in the 3rd dimension as the domain height of your simulation.
PA0003	dt_coupling is required to be set in atmosphere runtime parameters namelist	This error appears if the temporal interval for the data exchange dt_coupling is not explicitly set in case of runs with coupled atmosphere-ocean.
PA0004	mismatch between atmosphere and ocean model: dt_coupling (atmosphere) = "..." dt_coupling (ocean) = "..." ocean value is set to atmosphere value	For coupled runs the temporal interval for the data exchange dt_coupling must be explicitly set and must have the same value in both models (dt_coupling has to be set in PARIN and PARIN_O). See also coupled runs.
PA0005	dt_coupling < 0.0 is not allowed	This error occurs if an invalid value for dt_coupling is used in the parameter file. dt_coupling must be >= 0.0 and equal in both models (dt_coupling has to be set in PARIN and PARIN_O).
PA0006	time averaging of a static quantity ("...") is not provided	Remove this quantity from the list of output quantities in runtime parameter data_output, or just remove the _av from the respective string. Time averaging of static quantities is not provided, because these quantities do not change in time.
PA0007	illegal nesting boundary conditions: ...	Allowed values for nesting_bounds are '3d_nested', 'cyclic_along_x', 'cyclic_along_y', or 'vertical_only'.
PA0008	mismatch between atmosphere and ocean model: time from reference point (atmosphere) = "..." time_from reference point (ocean) = "..."	The simulated time from the reference point is stored internally in the variable time_to_be_simulated_from_reference_point. In coupled mode both times must be equal. This error might occur when precursor runs are used with different startup times and the coupling is initiated inappropiately. See coupled runs for a detailed description of the setup for precursor runs.
PA0009	dx in atmosphere is smaller than dx in ocean	Coupled runs allow to use different grid resolutions in atmosphere and ocean. It is, however, not allowed to use a finer grid resolution in the atmosphere than in the ocean.
PA0010	dy in atmosphere is smaller than dy in ocean	Coupled runs allow to use different grid resolutions in atmosphere and ocean. It is, however, not allowed to use a finer grid resolution in the atmosphere than in the ocean.
PA0011	3rd dimension of array "XXX" is larger than number of domain height levels: [size_of_3rd_dimension of XXX] > [nz+1]. Writing to file via MPI-IO not possible.	This is an internal error. If you did not add any user code to your simulation, please report this error via the trouble-ticket system. If you added user code and you try to write a 3-D variable to the restart files using the restart_data_mpi_io_mod module, the array you try to write is too large. It must not contain more entries in the 3rd dimension as the domain height of your simulation.
PA0012	nested child (id: ..) domain boundaries along x/y do not match the respective parent boundaries.	The nesting_parameter nesting_bounds has been chosen either 'cyclic_along_x', 'cyclic_along_y', or 'vertical_only', but the child does not exactly match the parent size along the respective direction(s). Adjust the child domain size respectively.
PA0013	illegal value given for loop_optimization: "..."	See parameter loop_optimization for allowed values, and check your parameter file.
PA0014	a non-flat topography does not allow ...	There are several features which do not work together with a non-flat topography. See parameter topography for possible restrictions and appropriately modify your parameter file. For a complete list of not allowed parameter settings due to a non-flat topography see check_parameters.f90.
PA0015	Using synthetic turbulence generator requires initializing_actions = "set_constant_profiles" or "read_restart_data"	When switching on the synthetic turbulence generator by setting use_synthetic_turbulence_generator = .TRUE., PALM has to be initialized using either constant profiles (initializing_actions = "set_constant_profiles") or loading data from a previous run (initializing_actions = "read_restart_data"). Other initialization actions do not support the synthetic turbulence generator.
PA0016	unknown solver for perturbation pressure: psolver = "..."	See parameter psolver for allowed values, and correct your parameter file.
PA0017	output of more than 300 profiles requested	The total sum of output profiles given via parameters data_output_pr and data_output_pr_user is greater than 300. You may either reduce the number of output profiles, or ask the PALM group (via the trouble-ticket system) to extend the bounds of PALM internal arrays to allow for more than 300 profiles.
PA0018	illegal value for data_output_masks or data_output_masks_user: ...	Possible reasons are: (a) a typo in the parameter file related to masked data output, (b) a user-defined variable has not been defined in user_check_data_output.f90, (c) the string length of the user-defined variable exceeds the current limits (see here). For possible output quantities see data_output_masks.
PA0019	unknown surface type: surface_type = "..."	See parameter surface_type for allowed values, and appropriately correct your parameter file.

PA0023	momentum_advec or scalar_advec = "..." is not allowed with timestep_scheme = "..."	The 5th order advection scheme is conditional unstable in conjunction with euler or runge-kutta-2 integration. Instead, use timestep_scheme = runge-kutta-3.
PA0024	unknown advection scheme: scalar_advec = "..."	See parameter scalar_advec for allowed values, and appropriately correct your parameter file.
PA0025	use_upstream_for_tke is set to .TRUE. because use_sgs_for_particles = .TRUE. and scalar_advec /= 'ws-scheme'	This is just a warning telling you that the simple upstream discretization is used for the advection term of the TKE equation instead of the one that you have set with parameter scalar_advec. This is required in case of using SGS velocity components for particle transport, because non-diffusiv advection schemes may cause large artificial vertical gradients near the surface, which create numerical instabilities in the particle transport. You can avoid output of this warning by explicitly setting parameter use_upstream_for_tke in the parameter file (initialization_parameters-NAMELIST).
PA0026	advection_scheme scalar_advec = "bc-scheme" not implemented for loop_optimization = "cache"	For the Bott-Chlond scheme loop_optimization = "vector" must to be set.
PA0027	unknown timestep scheme: timestep_scheme = "..."	See parameter timestep_scheme for allowed values, and appropriately correct your parameter file.
PA0028	negative weighting factor	A negative weighting factor might occur if the timestep is too long. Try to adjust dt.
PA0029	momentum advection scheme "..." does not work with timestep_scheme "..."	For timestep_scheme = 'runge-kutta-3' only momentum_advec = 'ws-scheme' or 'pw-scheme' gives a numerically stable solution.
PA0030	initializing_actions = "..." unkown or not allowed	See parameter initializing_actions for allowed values in initial runs (of a job chain). For a restart run, please set initializing_actions = 'read_restart_data' .
PA0031	initializing_actions = "set_constant_profiles" and "set_1d-model_profiles" are not allowed simultaneously	Set either initializing_actions = 'set_constant_profiles' in your parameter file, if the 3d-model shall be initialized with constant profiles, or set initializing_actions = 'set_1d-model_profiles' if the 3d-model shall be initialized with profiles of the (stationary) solution of the 1d-model.
PA0032	initializing_actions = "set_constant_profiles" and "by_user" are not allowed simultaneously	Set either initializing_actions = 'set_constant_profiles' in your parameter file, if the 3d-model shall be initialized with constant profiles, or set initializing_actions = 'by_user' , if the 3d-model shall be initialized with profiles to be provided by the user in routine user_init_3d_model of the user-interface.
PA0033	initializing_actions = "by_user" and "set_1d-model_profiles" are not allowed simultaneously	Set either initializing_actions = 'by_user' in your parameter file, if the 3d-model shall be initialized with profiles to be provided by the user in routine user_init_3d_model of the user-interface, or set initializing_actions = 'set_1d-model_profiles' , if the 3d-model shall be initialized with profiles of the (stationary) solution of the 1d-model.
PA0034	bulk_cloud_model = .T. is not allowed with humidity = .F.	It is necessary to turn on humidity for the use of cloud physics.
PA0035	Using synthetic turbulence generator requires bc_lr = "dirichlet/radiation"	The synthetic turbulence generator requires a non-cyclic boundary condition along x direction with an inflow at the left domain boundary.
PA0036	humidity = .TRUE. and sloping_surface = .TRUE. are not allowed simultaneously	If alpha_surface is set to a non-zero value in order to use an inclined surface, the parameter sloping_surface is internally set .TRUE.. I.e., in the case of alpha_surface /= 0.0 the simultaneous use of humidity = .TRUE. is not allowed.
PA0037	Using synthetic turbulence generator requires bc_ns = "cyclic"	The synthetic turbulence generator only supports non-cyclic boundary conditions at the left/right boundary. In north/south direction, cyclic boundary conditions must be set.
PA0038	turbulent_outflow = .T. requires bc_lr = "dirichlet/radiation"	When using the turbulent outflow method, non-cyclic boundary condition along the x direction must be used. See also turbulent_outflow.
PA0039	Using synthetic turbulence generator in combination with turbulent_inflow = .T. is not allowed	A turbulent inflow can only be generated by either the synthetic turbulence generator or the turbulence recycling method. Using both at the same time is impossible.
PA0040	LWC is not conserved during collision! LWC after condensation: ... LWC after collision: ...	LWC means liquid water content. This should not happen. Please write a ​ticket.
PA0041	plant_canopy = .TRUE. requires a non-zero drag coefficient, given value is canopy_drag_coeff = 0.0	When simulating a plant canopy, a non-zero canopy_drag_coeff must be set in the parameter file under NAMELIST &plant_canopy_parameters. The canopy model in PALM adds an additional sink/source terms to the momentum equations, the prognostic equation for temperature, and the subgrid scale turbulent kinetic energy equation. In case of humidity = .TRUE. or passive_scalar = .TRUE., an additional source/sink term is added to the prognostic equation of the respective scalar. If canopy_drag_coeff = 0.0, the additional terms equal zero and there would be no effect on the flow.
PA0042	use_top_fluxes must be .TRUE. in ocean mode	In ocean mode, fluxes at the water surface must be prescribed as driving boundary conditions. In atmosphere-ocean coupled runs, these fluxes are provided by the atmosphere run.

PA0046	baroclinity (ug) not allowed simultaneously with galilei transformation	The Galilei coordinate transformation (see galilei_transformation) is not allowed under baroclinic conditions (where the geostrophic wind varies with height). Modify either ug_surface or galilei_transformation, or set use_ug_for_galilei_tr = .FALSE. appropriately in the parameter file.
PA0047	baroclinity (vg) not allowed simultaneously with galilei transformation	The Galilei coordinate transformation (see galilei_transformation) is not allowed under baroclinic conditions (where the geostrophic wind varies with height). Modify either vg_surface, or galilei_transformation appropriately, or set use_ug_for_galilei_tr = .FALSE. in the parameter file.
PA0048	variable translation speed used for Galilei-transformation, which may cause instabilities in stably stratified regions	You have set both galilei_transformation = .TRUE. and use_ug_for_galilei_tr = .FALSE., which means that the translation velocity to be used in the Galilei transformation will be newly calculated after every timestep. From past experiences, this may cause numerical flow instabilities within stably stratified, non-turbulent regions.
PA0049	unknown boundary condition: bc_lr = "..."	See parameter bc_lr for allowed values, and appropriately correct your parameter file.
PA0050	unknown boundary condition: bc_ns = "..."	See parameter bs_ns for allowed values, and appropriately correct your parameter file.
PA0051	non-cyclic lateral boundaries do not allow psolver = "..." with FFT method = "..."	In case of non-cyclic lateral boundary conditions, the FFT solver requires the FFT methods fftw, temperton-algorithm, or singleton-algorithm. Please set parameter fft_method appropriately. Alternatively, you can choose the multigrid solver by setting the parameter psolver = 'multigrid' or 'multigrid_noopt' .
PA0052	non-cyclic lateral boundaries do not allow momentum_advec = "..."	Using non-cyclic lateral boundary conditions requires to use either the Wicker-Skamarock or the Piacsek-Williams advection scheme for momentum. You can choose one of these methods by setting the parameter momentum_advec.
PA0053	non-cyclic lateral boundaries do not allow scalar_advec = "..."	Using non-cyclic lateral boundary conditions requires to use either the Wicker-Skamarock or Piacsek-Williams advection scheme for scalar quantities. You can choose one of these methods by setting the parameter scalar_advec.
PA0054	non-cyclic lateral boundaries do not allow galilei_transformation = .T.	The Galilei coordinate transformation can only be used with cyclic horizontal boundary conditions. Either use bc_lr = bc_ns = 'cyclic' , or set galilei_transformation = .FALSE. in the parameter file.
PA0055	turbulent_inflow = .T. requires initializing_actions = 'cyclic_fill' or initializing_actions = 'read_restart_data'	Using a turbulent inflow requires that the 3d arrays have to be initialized by cyclically repeated data from a prerun or by restart data. Set parameter initializing_actions appropriately and follow the instructions at turbulent inflow.
PA0056	illegal value for reference_state: "..."	See parameter reference_state for allowed values, and appropriately correct your parameter file.
PA0057	boundary condition bc_e_b changed to "..."	You have set both bc_e_b = (u*)**+neumann, and constant_flux_layer = .FALSE., which is in conflict, since this type of boundary condition requires a constant flux layer. bc_e_b has been set to 'neumann' instead.
PA0058	unknown boundary condition: bc_e_b = "..."	See parameter bc_e_b for allowed values, and appropriately correct your parameter file.
PA0059	unknown boundary condition: bc_p_b = "..."	See parameter bc_p_b for allowed values, and appropriately correct your parameter file.
PA0060	Output at every timestep is wanted ("dt_..." = 0.0). The output interval is set to the fixed timestep dt = "..."s.	Occurs only when netcdf_data_format > 4 and dt /= -1 as an informative message. When using parallel NetCDF the output time interval must be >0. Using dt_do = 0.0 (output at every time step) is equal to setting the output interval to dt.

PA0062	unknown boundary condition: bc_pt_b = "..."	See parameter bc_pt_b for allowed values, and appropriately correct your parameter file.
PA0063	unknown boundary condition: bc_pt_t = "..."	See parameter bc_pt_t for allowed values, and appropriately correct your parameter file.
PA0064	both, top_momentumflux_u AND top_momentumflux_v must be set	If you want to give a momentum flux as top boundary condition, you have to give both components top_momentumflux_u and top_momentumflux_v at the same time.
PA0065	boundary_condition: bc_pt_b = "..." is not allowed with constant_heatflux = .TRUE.	You have tried to set both, a Dirichlet surface boundary condition for temperature (with bc_pt_b = 'dirichlet' ), and a surface sensible heatflux (with surface_heatflux /= 0.0).

PA0066	constant_heatflux = .TRUE. is not allowed with pt_surface_initial_change (/=0) = ...	If you give the sensible heatflux as surface boundary condition (using parameter surface_heatflux), you must not specify anything about the surface temperature at the same time (e.g. with parameter pt_surface_initial_change).
PA0067	boundary_condition: bc_pt_t = "..." is not allowed with constant_top_heatflux = .TRUE.	You have tried to set both, a Dirichlet boundary condition for temperature at the top (with bc_pt_t = 'dirichlet' ), and a sensible heatflux at the top (with top_heatflux /= 0.0). Please decide, if you like to give either the temperature or the heatflux as boundary condition at the top, and omit one of the two parameters in the parameter file.
PA0068	unknown boundary condition: bc_sa_t = "..."	See parameter bc_sa_t for allowed values, and appropriately correct your parameter file.
PA0069	boundary condition: bc_sa_t = "..." requires to set top_salinityflux	You have chosen a Neumann boundary condition for salinity at the top (by setting bc_sa_t = 'neumann' ), but you did not provide a salinity flux at the top. Please provide parameter top_salinityflux in the parameter file.
PA0070	boundary condition: bc_sa_t = "..." is not allowed with top_salinityflux /= 0.0'	You have tried to set both, a Dirichlet boundary condition for salinity at the top (with bc_sa_t = 'dirichlet' ), and a salinity flux at the top (with top_salinityflux /= 0.0). Please decide, if you like to give either the salinity or the salinity flux as top boundary condition, and omit one of the two parameters in the parameter file.
PA0071	unknown boundary condition: bc_..._b ="..."	See the respective parameter description in the documentation, and appropriately correct your parameter file.
PA0072	unknown boundary condition: bc_..._t ="..."	See the respective parameter description in the documentation, and appropriately correct your parameter file.
PA0073	boundary condition: bc_..._b = "..." is not allowed with prescribed surface flux	You have tried to set both, a Dirichlet surface boundary condition for humidity / passive scalar (with bc_q_b / bc_s_b = 'dirichlet' ), and a surface latent heatflux / scalar flux (with surface_waterflux / surface_scalarflux /= 0.0). Please decide, if you like to give either the surface humidity / scalar or the surface latent heatflux / scalar flux as boundary condition, and omit one of the two parameters in the parameter file.
PA0074	a prescribed surface flux is not allowed with ..._surface_initial_change (/=0) = ...	If you give the latent heatflux / scalar flux as surface boundary condition (using parameter surface_waterflux / surface_scalarflux), you must not specify anything about the surface humidity / scalar at the same time (e.g. with parameter q_surface_initial_change / s_surface_initial_change).
PA0075	boundary condition: bc_uv_b = "..." is not allowed with constant_flux_layer = .TRUE.	You have tried to set both, a Neumann surface boundary condition for horizontal velocity (with bc_uv_b = 'neumann' ), and a constant flux layer between the surface and the first vertical grid point (with constant_flux_layer = .TRUE.), which are contradicting conditions. Either set constant_flux_layer = .FALSE. or bc_uv_b = 'dirichlet' in the parameter file.
PA0076	unknown boundary condition: bc_uv_b = "..."	See parameter bc_uv_b for allowed values, and appropriately correct your parameter file.
PA0077	unknown boundary condition: bc_uv_t = "..."	See parameter bc_uv_t for allowed values, and appropriately correct your parameter file.

PA0079	rayleigh_damping_height = ... out of range [0.0, ...]	Adjust the value of rayleigh_damping_height in your parameter file to the allowed range. This error may appear if you have reduced the domain height in your current run (e.g. by reducing the number of vertical grid points) without adjusting the height at which Rayleigh damping shall start.
PA0080	preprocessor switch for fftw is missing	You have set fft_method = 'fftw' , but the fftw-code has not been activated by the corresponding cpp-preprocessor switch. Add '-D__fftw' to the %cpp_options line in the configuration file, touch file fft_xy.f90 (e.g. by executing command "touch trunk/SOURCE/fft_xy.f90" and re-compile (i.e. call palmbuild.
PA0081	"..." = 0.0 while using a variable timestep and parallel netCDF4 is not allowed.	When using parallel NetCDF output (netcdf_data_format>4) the number of output time levels must be calculated in the beginning of the simulation (see e.g. #PA0384). With a variable time step it is not possible to determine how many output time levels are needed to do an output at every time step. Therefore you have to set a fixed time step dt.
PA0082	number of statistic_regions = ... is not allowed	Adjust parameter statistic_regions in your parameter file to a value >= 0.
PA0083	normalizing_region = ... must be >= 0 and <= ... (value of statistic_regions)	The region number given by normalizing_region must be within the range [0, statistic_regions ]. Adjust normalizing_region appropriately in your parameter file.

PA0095	data_output_pr = ... is not implemented for bulk_cloud_model = .FALSE. and humidity = .FALSE.	The listed entries in the parameter file under data_output_pr are only available for bulk_cloud_model= .T. or bulk_cloud_model= .F. and humidity=.T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).

The listed entries in the parameter file under data_output_pr are only available for cloud_droplets= .T. or bulk_cloud_model=.T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).
PA0097	illegal value for data_output_pr or data_output_pr_user = "..."	No matching variable was found for the given identifier in the parameter file. Possible reasons are: (a) a typo in the parameter file, (b) a user-defined variable has not been defined in user_check_data_output.f90, (c) the string length of the user-defined variable exceeds the current limits (see here).
PA0098	illegal value for data_output_pr = "..."	No matching variable was found for the given identifier in the parameter file. This error is most likely related to a typo in the parameter file (a output variable was used that does not exist in PALM).
PA0099	netCDF: netCDF4 parallel output requested but no cpp-directive __netcdf4_parallel given, switch back to netCDF4 non-parallel output	netcdf_data_format > 4 has been set. This requires netCDF4 features including parallel file support, which have to be activated by setting the cpp-switches -D__netcdf4 and -D__netcdf4_parallel in the configuration file (%cpp_options). It also requires a netCDF4 library which supports parallel I/O. Set -I, -L and -l options in compile (%compiler_options) and load (%linker_options) options of the configuration file appropriately. Job will be continued with netcdf_data_format = netcdf_data_format - 2.
PA0100	momentum_advec of the restart run differs from momentum_advec of the initial run	The advection scheme for the momentum equations momentum_advec used in the restart run differs from the advection scheme used in the corresponding initial run. The advection scheme that is used in a restart run must be the same as the one that was used in the initial run.
PA0101	scalar_advec of the restart run differs from scalar_advec of the initial run	The advection scheme for scalar quantities scalar_advec used in the restart run differs from the advection scheme used in the corresponding initial run. The advection scheme that is used in a restart run must be the same as the one that was used in the initial run.
PA0102	number of output quantities given by data_output and data_output_user exceeds the limit of 500	The total number of output quantities listed in data_output and data_output_user exceeds the maximum of 500. To increase this limit, the standard PALM code has to be modified. In case you have little experience with the PALM code use a trouble ticket for a query to increase the maximum output number.

PA0107	output of "..." requires cloud_droplets = .TRUE.	The quantities ql_c, ql_v, ql_vp are only calculated in case of cloud_droplets = .T..
PA0108	output of "..." requires bulk_cloud_model = .TRUE.	For the output of some quantities related to clouds and humidity bulk_cloud_model= .T. must be set. For example, the water vapor mixing ratio qv requires bulk_cloud_model= .T.. Also, humidity = .T. must be set. If you want to simulate the humidity without condensation/evaporation processes, use only humidity = .T. and choose output quantity q for output of the water vapor mixing ratio.

PA0113	temporal averaging of precipitation amount "pra*" is not possible	The quantity precipitation_amount pra* listed in data_output contains already the summed precipitation of the last precipitation_amount_interval. Therefore, remove the substring _av of pra*.
PA0114	illegal value for data_output or data_output_user = "..."	No matching variable was found for the given identifier in the parameter file. Possible reasons are: (a) a typo in the parameter file, (b) a user-defined variable has not been defined in user_check_data_output.f90, (c) the string length of the user-defined variable exceeds the current limits (see here).
PA0115	illegal value for data_output = "..."	No matching variable was found for the given identifier in the parameter file. This error is most likely related to a typo in the parameter file (a output variable was used that does not exist in PALM). For possible output quantities see data_output.

PA0140	invalid soil layer configuration found (dz_soil_center(k) <= 0.0)	By setting zs (the center of the soil layers), the depths of the individual layers is calculated by PALM itself. This errors points towards a misconfiguration because a soil level is set within an already established soil layer. Check dz_soil.
PA0142	absolute temperature < 0.0 at zu(...) = ...	Within the PALM code (in bcm_init), the hydrostatic pressure profile is calculated for a neutrally stratified temperature profile t(z) = t_surface-g/c_p*z(k). If the height of the model domain is too large, the absolute temperature will become negative, which is not allowed. This error usually appears when both grid stretching is switched on and too many grid points along z are used. Try to reduce the number of grid points (nz), switch on the grid stretching at larger heights (see dz_stretch_level) or reduce the grid stretching factor (dz_stretch_factor).
PA0143	k=... j=... i=... ql_c=... part(...)%wf=... delta_r=...	This error occurs due to a spurious interaction of the production and depletion of supersaturations if the applied time step is too large. Please re-run the simulation with a shorter time step.
PA0144	#1 k=... j=... i=... e_s=... e_a=... t_int=... delta_r=... particle_radius=...	This error occurs if the droplet radius becomes negative. This might be related to a too long time step or an (artificial?) accumulation of super-droplets in one grid cell.
PA0145	illegal value for outflow_source_plane:...	The position of the source plane for the turbulent outflow method is not given or outside the model domain. Assign a value inside the model domain: dx <= outflow_source_plane <= nx*dx

PA0157	nonzero bulk velocity requires conserve_volume_flow = .T. and conserve_volume_flow_mode = "bulk_velocity"	The bulk velocity is used to prescribe a volume flow which then should be conserved. This, however, requires conserve_volume_flow = .T. and conserve_volume_flow_mode = "bulk_velocity".
PA0158	no vertical boundary condition for variable "..."	Routine advec_s_bc which calculates the advection term for scalar quantities using the Bott-Chlond scheme was called for a variable, which does not have a specific boundary condition implemented (Adding top and bottom boundaries according to the relevant boundary conditions is not possible). This should not happen. Please submit a trouble ticket.
PA0159	no term for component "..."	Routine buoyancy was called for a different wind component than the u/w-component while an inclined surface was used. In case of an inclined surface (see alpha_surface) the buoyancy term appears in the equation of motion of the w-component and u-component. There is no buoyancy term implemented for the v-component as the surface can only be inclined in x-direction and no buoyancy term is required for the v-component. This should not happen. Please submit a trouble ticket.
PA0160	non-cyclic lateral boundaries along x do not allow calculation of spectra along x	In case of non-cyclic conditions spectra would be largely affected by the non-cyclic lateral boundaries since this conflicts with the basic assumption used for the FFT that the spatial extention in the x and y-direction are infinitely large. See also data_output_sp.
PA0161	sorry, calculation of spectra in non parallel mode is still not realized	Calculation of spectra in non-parallel mode is not implemented.
PA0162	non-cyclic lateral boundaries along y do not allow calculation of spectra along y	In case of non-cyclic conditions spectra would be largely affected by the non-cyclic lateral boundaries since this conflicts with the basic assumption used for the FFT that the spatial extention in the x and y-direction are infinitely large. See also data_output_sp.
PA0163	run will be terminated because it is running out of job cpu limit remaining time: ... s termination time needed: ... s	In case that restart_time has not been set manually, PALM determines internally when a new restart run has to be carried out depending on the setting of termination_time_needed. Within the remaining time PALM will, for example, copy binary files for restart runs, archive or transfer result data. Have a look at Initialization and restart runs for further information.
PA0164	run will be terminated due to user settings of restart_time / dt_restart, new restart time is: ... s	A restart run is established by PALM due to the setting of restart_time and/or dt_restart and the new restart time is calculated.

Only certain files are allowed to be re-opened to prevent errors. If you are sure that the file can be re-opened without causing any errors, you may add the file-id to the list in routine check_open. See also the list of I/O-files.
PA0167	opening file-id ... not allowed for PE ...	Certain files are only allowed to be opened on a certain PE (in most cases only on PE0). Please check if your file can be opened on this PE and choose a different file-id.
PA0168	opening file-id ... is not allowed since it is used otherwise	Certain file-ids are reserved for files used temporarily outside of the main program. Please refer to the list of I/O-files and choose an unused file-id.
PA0169	current user-interface revision "..." does not match the required revision r....	You are using a user-interface which does not match the installed PALM revision. One reason might be that the default user-interface of the newest PALM revision has been changed by the PALM developers (e.g. because some parameters have been added to parameter-lists of subroutine calls). Please carefully read the source code change log, where these kind of changes are announced, and where also hints will be given for how to adjust existing user-interfaces.
PA0170	pointer for array ".." can't be associated	This is an internal error message from the pmc (PALM model coupler) which is responsible for data exchange in nested runs. Please submit a trouble ticket if you are sure that you did not modify the source code of the model coupler (pmc_interface_mod.f90).

PA0186	no spectra data available	This message occurs if the data_output_spectra routine is called but no spectra data was calculated through the routine calc_spectra. Check your spectra settings in the parameter file.
PA0187	not in use
PA0188	no system-specific fft-call available	You have set fft_method = system-specific. In this case you additionally have to set the cpp-preprocessor switches -D__ibm or -D__nec to specify the fft-library that you like to use. Calls to IBM/NEC-libraries are the only one implemented so far in the PALM code. Probably you forgot to set such a switch. Set the switch and do not forget to recompile the code.
PA0189	fft method "..." not available	See fft_method for the availabe methods that are implemented in PALM and modify the initialization-parameter fft_method in your NAMELIST file appropriately.
PA0190	flow_statistics is called two times within one timestep	Routine flow_statistics computes average profiles and further average flow quantities. It is only allowed to call this routine once during a time step (one timestep consists of several intermediate steps due to the selected time integration scheme).

PA0192	timestep has exceeded the lower limit dt_1d = ... s simulation stopped!	The time step of the 1D model is determined according to the diffusion criterion to assure a stable numerical solution. This error message means that the required minimum time step is several orders of magnitude smaller than dt_max_1d. The error message may indicate for unrealistic settings of e.g. boundary conditions or other NAMELIST parameters. Please also check if this error appears if you run without USERCODE. To compile and run the PALM and USERCODE with DEBUG-options might also give sometimes valuable hints.
PA0193	unknown initializing problem	This should not happen during the initialization of the model variables in the routine init_3d_model. Please submit a trouble ticket if you have run into this error.

The grid-dependent mixing length l_grid ( = Δ = (Δx Δy Δz)1/3 ) becomes larger than 2.7 * dx or 2.7 * dy starting from the reported height level k. Although PALM will not abort due to this warning, the chosen grid setup might lead to untrustworthy results. The reason for this is an unfavourable choise of grid anisotropy. To avoid this, make sure that the values of dx, dy, and dz do not differ too much from each other. In case of grid stretching, the settings of dz_stretch_level and/or dz_stretch_factor should be changed to ensure a smaller difference between dz(k) and dx and dy at the reported height level.

PA0229	nesting-setup requires different number of MPI procs (...) than provided (...)	This message appears for nested runs, if the total number of MPI processes for all nested domains given in the nestpar-NAMELIST is larger than the number of MPI processes which has been allowed for the run, e.g. with palmrun-option -X. (Attention: For hybrid OpenMP/MPI-runs the number of MPI processes allowed for the run is the number given by -X divided by the number of threads per MPI-task, as given with palmrun-option -O.) You either have to provide the run more resources (i.e. more cores) or you have to decrease the number of MPI processes in $nestpar.

PA0236	grid coarsening on subdomain level cannot be performed	The multigrid pressure solver halfs the number of grid points in each direction to get coarser grid levels. This is done for the subdomains on each PE until one of the directions cannot be divided by 2 without rest. If this is the case, the coarsest grid level of each subdomain are gathered on each PE for further coarsening. Before gathering, the coarsening must be done for the subdomain at least one time. You get this error messages for example with the following combination: nx = 60, ny = 60, nz = 60, npex = 4, npey = 2. With this combination, the subdomain on each PE has the size: nx = 15, ny = 30, nz = 60. The number of grid points in the x-direction of the subdomain cannot be divided by 2 and no coarsening is possible for the subdomains in this example. To avoid this error ensure that the number of grid points in each direction can be divided by 2 without rest on the subdomain of an PE at least one time. Therefor vary the number of grid points for the direction which does not fit by changing nx , ny or nz or adjust the number of processors by modifying the parameters npex or npey in order to get other subdomain sizes. In the example given above, you can avoid the error by changing nx or npex. For example setting nx = 64 leads to a subdomain of nx = 16, ny = 30, nz = 60. All numbers are now divisible by 2 without rest and the first coarser grid on the subdomain is then: nx = 8, ny = 15, nz = 30.
PA0237	multigrid gather/scatter impossible in non parallel mode	You are using the multigrid-solver and are running PALM in non-parallel mode (i.e. on a single processor core), but you have set a multigrid level (using parameter mg_switch_to_pe0_level) from where on data shall be collected on core 0 in order to allow for a further coarsening of the grid. Obviously, this does not make sense if only one core is used. Remove this parameter from your NAMELIST-file or set it to value -1 to switch of collection.
PA0238	more than 10 multigrid levels	You have selected the multigrid Poisson-solver (psolver = "multigrid") and a numerical grid which allows for more than 10 coarsening levels. This may happen for very large grids where the grid point numbers along x,y,z are given by 2n with n>10. The smallest grid which may cause this error would have 20483 points. However, depending on the chosen domain decomposition, much larger grids might be possible. Choose a different number of grid points to circumvent this problem.

Try to increase the residual limit, or fix the number of multigrid cycles (see mg_cycles). In any case, carefully check if the divergence of the velocity field is sufficiently reduced by the multigrid solver. This can be done by comparing the divergence before and after the call of the multigrid solver which is printed in the RUN_CONTROL file. If this error appears during the initial phase of a run (before the first timestep), the number of subdomain gridpoints along x/y/z probably do not allow sufficient coarsening of the grid. The number of gridpoints should allow for a division by two (without rest) at least 2-3 times.

The time step is determined according to the CFL criterion to assure a stable numerical solution. This error message means that the required minimum time step, determined from the three velocity components, is several orders of magnitude smaller than dt_max, or, in other words, that at least one of the velocity components got too large. Due to the large number of complex reasons it should be noted that this list is not complete, but it is intended to give general hints how to proceed in case of this error message. First, check for a unrealistic value of dt_max in the NAMELIST file. Moreover, this error message may indicate for unrealistic settings of e.g. boundary conditions or other NAMELIST parameters. For very small vertical grid spacing dz this error might also occur if roughness_length >= dz. Please also check if this error appears if you run without USERCODE. To compile and run the PALM and USERCODE with DEBUG-options might also give sometimes valuable hints. In case the land-surface model or the building-surface model is employed, surface temperatures might had become unstable during the time-integration. One known issue is e.g. the presence of metal surfaces pavement_type = 7, where the integration of surface tempertures can become unstable, producing unrealistically high or low surface sensible heat fluxes. Please check for possibly mis-represented settings in your static input file. List to be continued.
PA0313	LAD/BAD profile is omitted at building grid points which have been artificially created by the topography filtering	Due to numerical reasons one-grid point cavities in a given topography are automatically filtered, i.e. replaced by a building with height based on the surrounding buildings.

In that case, data must be interpolated from the atmosphere to the ocean grid. Therefore, it must be ensured that each atmosphere grid interval contains the same number of ocean gridpoints. This is ensured if the following holds: with the number of grid points along x for the ocean and atmosphere model, respectively. To avoid this error ensure that the above equation is fulfilled, i.e. that nx_o+1 is a multiple of nx_a+1.

An initial wind profile that deviates too much from the geostrophic wind profile will cause strong inertia oscillations and thus the mean flow will take a long time to become steady state. The strength of the inertia oscillation can be significantly reduced, when the initial wind profile is set to the steady-state wind profile that might be obtained by a low-cost precursor simulation with a small domain and coarser grid spacing.

Within this process it could happen that the size of the windows is too small due to a very large number of particles that need to be transferred between the domains. Either choose a smaller amount of particles or change the internal limit of max_nr_prts_in_rma_win from 100000 to a higher value.

PA0482	Version of binary SVF file "..." does not match the version of model "..."	This error occurs when radiation data from the file SVFIN is read and the precursor run was carried out with a different svf binary version than the main run. Repeat the precurser with the current version or carry out the main run with the same version as the precursor. You can check the svf binary version number which is required for the main run in radiation_model_mod.f90​.
PA0483	Wrong number of SVF or CSF	This error can happen if svf data is read from file SVFIN (e.g. during manual restarts). The local number of sky view factors and canopy sink factors for calculating surface reflection of radiation has to be the same between the precursor run and the main run. Be sure that you create the svf binary data with the same version as the version of the main run.
PA0484	The lowest level where vertical stretching is applied have to be greater than ...	The wind turbine model implemented in PALM does not consider a stretched grid. Therefore grid stretching should only be applied well above the region where the wind turbine model is active. Please adjust dz_stretch_level_start accordingly.

PA0492	initializing_actions = "..." has been changed to 'interpolate_from_parent' in child domain.	This is an informative message. In a nested run, only 'read_restart_data' (in case of a restart) or 'interpolate_from_parent' are allowed for initializing_actions in child domain even though the constant-profiles initializations for the prognostic variables will be overwritten by pmci_child_initialize and pmci_parent_initialize. This is, however, important e.g. to make sure that diagnostic variables are set properly. An exception is made in case of restart runs and if user decides to do everything by its own.

Be sure that you created the svf binary data with the same version as the version of the main run. Otherwise submit a trouble ticket.
PA0495	optimized multigrid method requires nz to be even	You are using the optimized multigrid method, which requires nz to have an even value. Change nz in your parameter file, or choose psolver = 'multigrid_noopt' (but be aware that with an uneven value of nz the multigrid solver can only use one grid level, so you will have no multi grid levels at all and hence convergence will be very low!).
PA0496	The lowest level where vertical stretching is applied have to be greater than ...	The radiation model does not consider a stretched grid. The assumption of a uniform grid is necessary in parts below the top layer of urban surface (index height nzut). Please adjust dz_stretch_level_start accordingly.

PA0503	z0* exceeds 0.5 * surface-layer height at ... surface grid point (i,j) = (...,...)	Monin-Obukhov similarity is assumed between the surface and the first computational grid point normal to the surface. Because of the staggered grid, the distance between these two points is half of the grid spacing in the respective direction, i.e. dz/2 in vertical direction. The height z = dz/2 defines the top of the (analytical) logarithmic layer z_mo (the surface layer height). Functions like ln(z_mo/z0), where z0 is the roughness length, are used to calculate characteristic surface layer variables like u* or theta*. This mathematically requires that z_mo > z0, or in other words, that z0 < dz/2. In case you have run into this error, you either need to reduce the roughness length z0 (via namelist parameter roughness_length or in the static driver) or enlarge the grid spacing dz. Same holds for roughness length z0h for temperature and z0q for moisture. Attention: This message is given only once (for the first grid point where the exceedance has been detected). Be aware that there might be more grid points where z0 exceeds the surface-layer height. In case of water surfaces z0 is automatically calculated each time step via the Charnock relation and respectively checked. No information about grid point location(s) is given for that case. More than one location may have been detected. Set initialization parameter allow_roughness_limitation = .TRUE. in order to allow for an automatical limitation of z0 to a maximum value of 0.5 * z_mo, which is equivalent to 0.25 * dz.

This is not the case here, and so the sky view factors are re-calculated (which requires some computational resources).
PA0518	total number of grid points along x and y in file SVFIN do not match current run. nx_on_file = ..., ny_on_file = ..., nx = ..., ny = ...

PA0648	No grid coarsening possible, multigrid approach effectively reduces to a Gauss-Seidel scheme.	The convergence of the pressure solver might be insufficient and the simulation can become unstable. You should try to adjust the number of subdomain grid points in a way that each of (nx+1)/npex, (ny+1)/npey, and nz contain power-of-two (2n) factors with at least n = 2 or larger. Be aware that you can change both, the total number of gridpoints of the total domain, and/or the number of PEs. Alternatively, in case that you cannot change your grid or virtual processor grid, you may try to increase the number of Gauss-Seidel iterations (ngsrb) to improve convergence, but this approach is very limited.

Otherwise anterpolation is not possible. The absolute minimum number of parent-grid cells covered in x- and y-directions is 3 + 2*anterpolation_buffer_width, and 2 + anterpolation_buffer_width in z-direction. However, it is recommended that child domains cover much larger number of parent-grid cells. This error message is only given if nesting_mode = 'two-way'.
PA0653	Anterpolation_buffer_width value too high, reset to 0	In case of a marginally small child domain (see PA0652 above), the user is warned and anterpolation_buffer_width is set to 0 (the default value is 2) so that the minimum criteria (see PA0652 above) for the child domain size in terms of the number of parent-grid cells covered are satisfied. However, it is recommended that child domains cover much larger number of parent-grid cells. This warning is only given if nesting_mode = 'two-way'.
PA0654	Anterpolation_buffer_width value too high, reset to the default value 2	In case of too wide anterpolation buffer, the user is informed and anterpolation_buffer_width is reset to its default value 2 so that the minimum criteria (see PA0652 above) for the child domain size in terms of the number of parent-grid cells covered are satisfied. However, it is recommended that child domains cover much larger number of parent-grid cells. This informative message is only given if nesting_mode = 'two-way'.

Be careful near the lateral boundaries with respect to the surface energy balance terms.
PA0661	namelist file "PARIN" or "PARIN_O" not found! Please have a look at the online description of the error message for further hints.	The origin of this error can have several reasons. Most likely, the activation string of the palmrun command was incorrect. You have to assure that the correct activation string is set so that the parameter namelist is recognised by palmrun (per default, this is 'd3#' for normal runs or 'd3r' for restarts). If you use several strings within the list of activation strings, make sure that each string is separated by a blank, i.e. do not write 'd3#restart' but 'd3# restart'. If you used a modified version of .palm.iofiles, there is probably an incorrect linkage between the PARIN file and the actual file inside the INPUT directory. Please refer to the documentation of palm_iofiles for how to correctly configure this file.
PA0662	no output file type selected for surface-data output! Set at least either "to_vtk" or "to_netcdf" to .TRUE.	Surface-data output was requested without specifying a file type to store the data in. When requesting surface-data output, either 'to_vtk' or 'to_netcdf' or both must be set to true.

As a consequence the model output is deactivated if version 3 is used. Keep in mind that just providing a NetCDF4 library is not sufficient. You also need to re-compile the PALM code with preprocessor directive -D__netcdf4 and runtime parameter netcdf_data_format set to 4.

If you specified any data-output quantity for a xy-, xz-, or yz-cross section via data_output, then you need to also specify the location of at least one corresponding cross section via section_xy, section_xz, or section_yz.
PA0682	number of subdomain grid points along x (...) is smaller than the number of ghost points (...)	In order to allow parallelization, the total computational domain is split into subdomains along x and y. The number of subdomains equals the number of cores used for the run. Ghost grid layers are added to the subdomains. The number of grid points along x in a subdomain must not be smaller than the number of ghost layers. You may either increase the total number of grid points nx or reduce the number of cores used for the run.
PA0683	number of subdomain grid points along y (...) is smaller than the number of ghost points (...)	In order to allow parallelization, the total computational domain is split into subdomains along x and y. The number of subdomains equals the number of cores used for the run. Ghost grid layers are added to the subdomains. The number of grid points along x in a subdomain must not be smaller than the number of ghost layers. You may either increase the total number of grid points ny or reduce the number of cores used for the run.
PA0684	Found building surface on non-building coordinates (xs, ys, zenith, azimuth): "xs, ys, zenith, azimuth"	If the variable building_surface_pars has been specified within a static driver, the coordinates xs/ys/zs define the location of a horizontal/vertical buildings surface, while zenith/azimuth define the orientantion of the surface (upward-, northward-, southward-, eastward-, westward-facing). In case this error message appears, the coordinates xs, ys, zs, zenith, and azimuth describing a surface element do not match with the location of a building. Even if xs, ys, zs, are prescribed correctly, mismatches in zenith and azimuth may cause this error. In such a case, please check carefully your pre-processor code that you used to create the static driver. Further information about the data input for surface elements can be found here.
PA0686	relative material fractions do not sum-up to one at some surfaces	If building_pars is specified within a static input file, all parameters indicating the relative fraction of wall / window / green surfaces must be given and sum up to 1. This requirement is violated. Check and correct the static driver respectively.
PA0688	surface fractions at grid point (j,i) = ( ) are all zero.

PA0690	end_time of the simulation exceeds the time dimension in the dynamic input file.	Time dimension in <run_identifier>_dynamic must cover the entire simulation time.
PA0691	Offline nesting: time dimension must start at time_utc_init.	Time dimension in <run_identifier>_dynamic must start at the start of the simulation in time utc. For example, for a simulation starting at 7 am in UTC+3 time, this is 14400.
PA0692	end_time of the simulation exceeds the time dimension in the salsa input file.	Time dimension in <run_identifier>_salsa must cover the entire simulation time.
PA0693	None of the aerosol chemical components in <run_identifier>_dynamic correspond to ones applied in SALSA.	None of the chemical components given in composition_name in <run_identifier>_dynamic correspond to the ones applied in SALSA. Please check the file and spelling.
PA0694	Missing emission_mass_fracs in <run_identifier>_salsa	Variable emission_mass_fracs missing from <run_identifier>_salsa.
PA0695	salsa_emission_mode = "parameterized", but the street_type data is missing.	When salsa_emission_mode = "parameterized", the variable street_type must be provided in <run_identifier>_static.
PA0697	The mixing ratio exceeds the saturation mixing ratio	The mixing ratio must not exceed its saturation mixing ratio by more than 2 percent. Higher values are physically unrealistic and will not be observed in the atmosphere. In case cloud physics are considered, oversaturation would create strong convection leading to unpredictable model behavior. Further, oversaturated mixing ratios have implications in the land-surface model, where moisture might condense immediately at the surface, creating very high surface fluxes. Note, an error message is given in the initial run, while only a warning is given when moisture exceeds its saturation value in a restart run.
PA0698	Unclassified surface element at grid point (k,j,i) =	Input data is not defined consistently. Please contact the Palm support. One reason for this could be that input data for land-surfaces and buildings are provided in the static driver, but one of the energy-balance models for buildings or land-surfaces are disabled.
PA0699	Bottom and top boundary are treated equal	This is just an informative message. It tells you that the regions close to the bottom and top boundaries are treated physically and numerically equal. This is not necessarily the case for normal atmospheric runs.
PA0700	dz should be equal close to the boundaries due to symmetrical problem	To get realistic results of a closed channel flow, it is necessary to treat bottom and top boudary region the same. This includes the grid spacing.
PA0701	A constant flux layer is not allowed if a closed channel shall be used	So far, the constant flux layer approach is only implemented for the bottom boundary but bottom and top boundary shall be treated equal for closed channel flows. Therefore, it is not allowed.
PA0702	The ocean mode is not allowed if a closed channel shall be used	self-explanatory
PA0703	A closed channel requires the upwind scheme of Wicker and Skamarock as the advection scheme	Only the upwind scheme of Wicker and Skamarock is realized and tested for a symmetric degradation of the advection scheme (from 5th, to 3rd to 1st order) close to the bottom and top boundary.

Check the respective line given in the error message. a) The number of columns (ncols) is less than nx+1. b) The number of rows (nrows) is less than ny+1. Solution: Make sure that ncols matches nx+1 and that nrows matches ny+1.
PA0705	If virtual measurements are taken, the number of surrounding grid points must not be larger than the number of ghost points - 1	When virtual measurements are taken, data is sampled at given station grid coordinates. It is possible that also the adjoining grid points can be sampled, however, the number of grid points additionally sampled in each direction must not be larger than the number of ghost points - 1 to avoid any segmentations faults. In the future we will improve this to allow a more flexible number of offset grid points.

PA0817	Mesoscale nesting requires initializing_actions = "read_from_file".	If lateral and top boundary conditions are obtained from a mesoscale model simulation, the initial profiles of the velocity components, potential temperature and mixing ratio need to be in line with the mesoscale data. As boundary conditions from mesoscale model data are handed over via the dynamic input file, the initial profiles should also handed over this way. If other initial data is used instead, this could result in large discrepancies between the initial data and the boundary data at the inflow boundaries, which can lead to strong numerical oscillations. In particular for the mixing ratio, this could produce even values close to zero or supersaturated conditions, possibly leading to numerical instabilities in conjunction with the energy-balance schemes.

PA0828	Initial values of soil moisture are < 0.0.	The initial soil moisture must be set to values >= 0.0. Set soil_moisture to reasonable values, either by setting the respective namelist parameter or by providing initial soil moisture values via the dynamic input file.
PA0829	The mixing ratio exceeds the saturation mixing ratio. First exceedance after X seconds of simulated time. No further warning will be given. Please check your results carefully.	The water vapor mixing ratio exceeds its saturation value. In case condensation processes are switched-on by using the bulk-cloud model, this is usually no issue because water vapor is removed. However, in case no condensation processes are enabled, the physical setup might become unrealistic. Depending on the level of supersaturation, the buoyancy term can become unrealistic. Further, in case of the land- or urban-surface model, water vapor is partly removed at the surface due to dew formation, which can become unrealistically large, yielding to unrealistic sensible and latent surface heat fluxes, potentially even causing simulation crashes. If this warning pops-up, please check your results carefully.

PA0844	Dynamic input files provides too few time levels for turbulent inflow: ... is less than <end_time>.	For the read-from-file inflow method, the covered time interval of the inflow boundary data in the dynamic input file needs to be larger/equal the simulation time.
PA0845	Dimension "time_inflow" in dynamic input file must start at 0.0s.	For the read-from-file inflow method, the time dimension starts at 0.
PA0846	Dimension "time_inflow" in dynamic input file contains fill values.	Fill values are not allowed in the time dimension.
PA0847	input_block_size must be smaller or equal than 2 x the subdomain size in x-direction, which is: nxr - nxl + 1, and larger or equal than 2.	In the read-from-file inflow method, the input block size of the boundary data can be customized, in order to allow input of multiple timesteps at once to avoid NetCDF IO every timestep. In order to contrain the input size to avoid any memory exceedance, the size of input boundary data is limited to maximum two three-dimensional arrays. Please check the domain decomposition in the RUN_CONTROL or HEADER file and decrease input_block_size accordingly. Alternatively, the domain-decomposition along the x-dimension can be changed via the namelist parameter npex.

NC****	**** contains numbers in the range from 1-521	Internally, PALM calls the netCDF function NF90_STRERROR which returns an error message string provided by netCDF. Hence, no exact assignment between PALM error number and netCDF error string can be given. Most of the netCDF errors should never appear if the default code is used. The following list gives errors which may be caused by wrong steering or errors due to problems in the user interface.
NC0079	String match to name in use	A netCDF variable name has been used twice. Possible reasons: a variable in the parameter file has been listed twice (e.g. in data_output) or a variable name that has been defined in the user interface is already used by PALM.
NC0253	Name contains illegal characters	netCDF variable names consist of arbitrary sequences of alphanumeric characters. These names are e.g. assigned by the user in the user-interface to variables dots_label or dopr_label. Due to the netCDF convention, they must not start with a digit. Also, usage of / as special character is not allowed. Older netCDF versions (before 3.6.3) have further restrictions on special characters. Please check if your string settings in the user-interface follow the above rules.
