PALM error messages

The following list displays the error messages reported by PALM. Each error message is identified by a unique message identifier which is composed of two letters and a four digit number. The second column contains the error message as reported in the job protocol (see here?). The third column explains the error and possible reasons in more detail, and also gives suggestions how to solve the problem.

Message identifier	Error message	Explanation
PA0001	"host" is not set. Please check that environment variable "localhost" is set before running PALM	By default, PALM gets the "host" value from reading the NAMELIST envpar, which is automatically provided in a local file named ENVPAR, if PALM is run with scripts mrun or palm_simple_run. You may check the contents of file ENVPAR (e.g. by running mrun with option -B (preventing that the temporary working directory containing this file is automatically deleted when mrun is finished), or submit a trouble ticket.
PA0002	illegal coupling mode: ...	This message is related to the atmosphere-ocean coupling implemented in PALM. Internally, the variable coupling_mode defines the coupling setup used for the current respective model run. It may have one of the values "atmosphere_to_ocean" (atmospheric part of a coupled run), "ocean_to_atmosphere (ocean part of a coupled run), "precursor_atmos" (a precursor atmosphere run), "precursor_ocean" (a precursor ocean run), or "uncoupled" (atmosphere or ocean run without any intended coupling). This error message means that the initialization of the coupling did fail because coupling_mode has a value different from the ones mentioned before. Possible reasons might be trying a coupling between two atmosphere runs (or two ocean runs), or problems with the mrun script.
PA0003	dt_coupling is not set but required for coupling mode "..."	This error appears if the temporal interval for the data exchange dt_coupling is not explicitly set in case of runs with coupled models (e.g. atmosphere - ocean).
PA0004	coupling mode "...": dt_coupling = ... is not equal to dt_coupling_remote = ...	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.
PA0005	coupling mode "...": dt_coupling <= 0.0 is not allowed and is reset to MAX(dt_max(A,O)) = ...	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.
PA0006	coupling mode "...": restart_time = ... is not equal to restart_time_remote = ...	restart_time has not been set properly (equal) in the atmosphere and ocean parameter file. See also coupled runs.
PA0007	coupling mode "...": dt_restart = ... is not equal to dt_restart_remote = ...	dt_restart has not been set properly (equal) in the atmosphere and ocean parameter file. See also coupled runs.
PA0008	coupling mode "...": simulation_time_since_reference = ... is not equal to simulation_time_since_reference_remote = ...	The simulated time is stored internally in the variable simulation_time_since_reference. 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 not larger or equal than dx in ocean	Coupled runs allow to use different grid resolutions in atmosphere and ocean. It is, however, not possible to use a finer grid resolution in the atmosphere than in the ocean.
PA0010	Domain size in x-direction is not equal in ocean and atmosphere	Coupled runs are only possible, if the horizontal model domain size is equal in both, atmosphere and ocean. Check the settings for dx, dy, nx and ny to avoid this error.
PA0011	dy in atmosphere is not larger or equal than dy in ocean	Coupled runs allow to use different grid resolutions in atmosphere and ocean. However, it is not allowed to use a finer grid resolution in the atmosphere than in the ocean.
PA0012	Domain size in y-direction is not equal in ocean and atmosphere	Coupled runs are only possible, if the horizontal model domain size is equal in both, atmosphere and ocean. Have a look at the settings for dx, dy, nx and .ny? to avoid this error.
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.
PA0015	ocean = .T. does not allow ...	There are several features which do not work within PALM's ocean mode. See parameter ocean for possible restrictions and appropriately modify your parameter file.
PA0016	unknown solver for perturbation pressure: psolver = "..."	See parameter psolver for allowed values, and correct your parameter file.
PA0017	Vertical grid stretching is not allowed together with particle advection.	With the currently implemented spatial interpolation of flow quantities on the respective particle positions, a constant vertical grid spacing must be used.
PA0018	ros_count > 5 in Rosenbrock method	The Rosenbrock method is used if curvature and solution effects are included in the calculation of cloud droplet growth due to condensation (see curvature_solution effects). This algorithm may lead to unreasonable results, if the external conditions, especially the supersaturation, significantly changes between two PALM time steps. In that case, the algorithm will be carried out again with a smaller internal time step. The limits, which decide weather a result is reasonable or not, are only tested for a certain range of relative humidities and cloud droplet sizes. If this error appears, the result after 5 recalculations of the Rosenbrock algorithm is still regarded as unreasonable. Thus the limiting values may not be suitable for the current conditions and need to be adjusted in PALM's source code (see file lpm_doplet_condensation.f90 in the repository).
PA0019		error number not in use
PA0020	unknown multigrid cycle: cycle_mg = "..."	See parameter cycle_mg for allowed values, and appropriately correct your parameter file.
PA0021	unknown fft-algorithm: fft_method = "..."	See parameter fft_method for allowed values, and appropriately correct your parameter file.
PA0022	unknown advection scheme: momentum_advec = "..."	See parameter momentum_advec 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 set .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 (inipar-NAMELIST). This warning will not occur if
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: ...	The weighting factor of the cloud droplets is recalculated during the calculation of the droplet growth due to collision and coalescence. This error appears, if the newly calculated value for the weighting factor is negative and the hall_fast or wang_fast collision kernel has been used (see collision_kernel). A possible reason may be illegal values of the collision kernel.
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	cloud_physics = .T. is not allowed with humidity = .F.	It is necessary to turn on humidity for the use of cloud physics.
PA0035		error number not in use
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	negative weighting factor: ...	The weighting factor of the cloud droplets is recalculated during the calculation of the droplet growth due to collision and coalescence. This error appears if the newly calculated value for the weighting factor is negative and the 'hall' or 'wang' collision kernel is used (see collision_kernel). It may be caused by illegal values of the collision kernel. Please submit a trouble ticket if you have run into this error.
PA0038	humidity = .TRUE. and passive_scalar = .TRUE. is not allowed simultaneously'	In PALM, the same equation and internal variable is used for transport of humidity and scalar quantity. This quantity can either be the humidity or a passive scalar, but not both at the same time.
PA0039	negative weighting factor: ...	The weighting factor of the cloud droplets is recalculated during the calculation of the droplet growth due to collision and coalescence. This error appears if the newly calculated value for the weighting factor is negative and the 'palm' collision kernel is used (see collision_kernel). It may be caused by illegal values of the collision kernel. Please submit a trouble ticket if you have run into this error.
PA0040	LWC is not conserved during collision! LWC after condensation: ... LWC after collision: ...	This should not happen. Please write a ​ticket.
PA0041	simulating a plant canopy 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 &canopy_par. 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.
PA0043	ABS( alpha_surface = ... ) must be< 90.0	Upright surfaces are not allowed in case of sloping surfaces.
PA0044	dt = ... <= 0.0	The parameter dt (time step for the 3d-model) must not be set to a value <= 0.0.

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.

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 = "..."	Using non-cyclic lateral boundary conditions requires the multigrid method for solving the Poisson equation for the perturbation pressure. You can choose this method by setting the parameter psolver = 'multigrid' .
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'	Using a turbulent inflow requires that the 3d arrays have to be initialized by cyclically repeated data from a prerun. Set parameter initializing_actions appropriately.
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 desired ("dt_..." = 0.0). Setting the output interval to the fixed timestep dt = "..."s.	Occurs only when netcdf_data_format > 4 and dt /= -1. 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.

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). Please decide, if you like to give either the surface temperature or the surface heatflux as boundary condition, and omit one of the two parameters in the parameter file.
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 constant_top_salinityflux = .TRUE.'	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.

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.

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.
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.

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.
PA0084	dt_sort_particles is reset to 0.0 because of cloud_droplets = .TRUE.	Using particles as cloud droplets (cloud_droplets = .TRUE.) requires sorting of the particle array after each timestep. This warning means, that the respective steering parameter (dt_sort_particles) for the resort-interval has been automatically reset to 0.0, in order to force a resort after each timestep. Not available from release 4.0 on.
PA0085	averaging_interval = ... must be <= dt_data_output = ...	The averaging_interval for output data must be smaller or equal to the output interval given by dt_data_output. Adjust settings of these variables appropriately in the parameter file.

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 (%copts) and load (%lopts) 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 100	The total number of output quantities listed in data_output and data_output_user exceeds the maximum of 100. 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.

PA0108	output of "..." requires cloud_physics = .TRUE.	For the output of the water vapor content qv (specific humidity) set cloud_physics = .T. to switch on the condensation scheme. 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 specific humidity.
PA0109	output of "..." requires ocean = .TRUE.	The quantities rho and sa are only calculated in case of ocean = .T..
PA0110	output of "..." requires passive_scalar = .TRUE.	The output of the passive scalar s is only available if the prognostic equation for a passive scalar is solved by setting passive_scalar = .T..
PA0111	illegal value for data_output: "..." only 2d-horizontal cross sections are allowed for this value	The listed quantities are pure two-dimensional xy-cross-sections.

If output of particle data is switched on (see dt_write_particle_data), the size of the particle array, given on each processor by maximum_number_of_particles, is not allowed to increase during the run, when the netCDF3 data format is used, because netCDF3 allows only one unlimited dimension, which is the time dimension. Anyhow, PALM tries to increase the size of the particle array, if the number of particles in a subdomain becomes larger than the size of this array. This may happen because of a flow convergence or because new sets of particles are released (see dt_prel). This problem can be avoided by using the netCDF4 data format (netcdf_data_format > 2), which allows more than one unlimited dimension. Alternatively, maximum_number_of_particles can be given a sufficiently large value.

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.
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.

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.

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. 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.

PA0339	coupling mode "...: nx+1 in ocean is not divisible without remainder with nx+1 in atmosphere	For the coupling between atmosphere and ocean, a smaller grid length in the x-direction can be chosen for the ocean, so that the ocean has more grid points in the x-direction then the atmosphere. In this case, the information must be interpolated for the data exchange between atmosphere and ocean. Therefor it must be ensured that each interpolation interval has the same number of gridpoints. This is ensured if the following equation is fulfilled: with as the number of grid points in the x-direction for the ocean and atmosphere model, respectively. To avoid this error ensure that the equation above is fulfilled.

PA0347	maxtry > 40 in Rosenbrock method	Error may appear if curvature and solution effects are included in the calculation of droplet growth by condensation (see curvature_solution effects. It means that the Rosenbrock method, used for integrating the stiff droplet growth equation, was unable to find an internal timestep which gives a sufficiently small truncation error within 40 tries. So far, this problem has not appeared. It might happen if some of the cloud physics parameters, which determine the growth by condensation, are given unrealistic values or if the droplet radius is extremely small.
PA0348	zero stepsize in Rosenbrock method	Error may appear if curvature and solution effects are included in the calculation of droplet growth by condensation (see curvature_solution effects. It means that within the Rosenbrock method, used for integrating the stiff droplet growth equation, the internal timestep has become zero, so that the integration cannot be performed. So far, this problem has not appeared. It might happen if some of the cloud physics parameters, which determine the growth by condensation, are given unrealistic values or if the droplet radius is extremely small.
PA0349	use_sgs_for_particles = .TRUE. not allowed with curvature_solution_effects = .TRUE.	When Lagrangian particles are used as cloud droplets, they are only allowed to be transported with the resolved-scale flow. The application of the stochastic subgrid-scale transport model is limited to passively advected particles. Since cloud droplets have inertia, a transport with the SGS model would give wrong results.

In this case the geostrophic wind profiles and large scale subsidence profile prescribed in LSF_DATA cannot be used.
PA0374	Nudging requires large_scale_forcing = .T.. Surface fluxes and geostrophic wind should be prescribed in file LSF_DATA	In order to use nudging it is required to use large_scale_forcing = .T., too. The surface values and profiles needed in LSF_DATA should correspond to the data provided in NUDGING_DATA.

In case of parallel NetCDF output, the time dimension is limited for increasing the performance. The number of time levels is calculated at the beginning of the simulation by the formula: The parameters end_time, skip_time_do2d_xy and dt_do2d_xy can be set by the user. If this limit is exceeded, this warning is given and an output of xy-sections is not done anymore. This could be the case if the simulated time exceeds the given end time by the length of the given output interval. In this case, the user can start a restart run and give an output at the beginning.

The number of time levels is calculated at the beginning of the simulation by the formula: The parameters end_time, skip_time_do2d_yz and dt_do2d_yz can be set by the user. If the calculated number of maximum time levels between the initial run and a restart run changed by modifing on of the parameters above, a new output file is created.

PA0393	data_output_pr = ... is not implemented for large_scale_forcing = .FALSE.	The listed entries in the parameter file under data_output_pr are only avialable for large_scale_forcing = .T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).
PA0394	data_output_pr = ... is not implemented for nudging = .FALSE.	The listed entries in the parameter file under data_output_pr are only avialable for nudging = .T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).
PA0395	zu(nzt+1) = ... m is higher than the maximum height in LSF_DATA which is ...m. Interpolation on PALM grid is not possible.	LSF_DATA has a maximum vertical height that is smaller than the vertical extent of the grid used in PALM. Hence, interpolation of the LSF_DATA onto the PALM grid is not possible. Reduce either the vertical extent of the PALM modeling domain or enlarge the LSF_DATA file correspondingly.
PA0396	The usage of use_subsidence_tendencies requires large_scale_subsidence = .T..	If use_subsidence_tendencies is used, subsidence tendencies for temperature and humidity are read in from the external file LSF_DATA. However, these tendencies can only be applied to the prognostic variables if large_scale_subsidence = .T..
PA0397	The usage of use_subsidence_tendencies requires large_scale_forcing = .T..	If use_subsidence_tendencies is used, subsidence tendencies for temperature and humidity are read in from the external file LSF_DATA. This requires large_scale_forcing = .T..
PA0398	run will be terminated because user forced a job finialization using a flag file: DO_STOP_NOW: "..." DO_RESTART_NOW: "..."	The user can force an unscheduled termination/restart of the running job by creating one of the flag files DO_STOP_NOW or DO_RESTART_NOW in the temporary directory of the job.
PA0399	lsm requires setting of bc_pt_b = "dirichlet" and bc_q_b = "dirichlet"	In case the land surface model (LSM) is used, the surface fluxes have to be calculated by means of surface values of potential temperature and humidity (that are provided by the LSM), which reflects setting dirichlet boundary conditions.
PA0400	lsm requires ...	When using the LSM it is required to use a constant flux layer and a radiation scheme.
PA0401	veg_type = 0 (user defined) requires setting of ...	In case a user-defined vegetation is used, all LSM parameters must be explicitly set by the user.
PA0402	data_output_pr = ... is not implemented for land_surface = .FALSE.	The chosen quantity is related to the LSM, but the LSM was not activated.

PA0409	output of ... requires radiation = .TRUE. and radiation_scheme = "rrtmg"	The desired output (here: surface albedos) is only available when using radiation_scheme = "rrtmg"
PA0410	radiation_scheme = "clear-sky" in combination with albedo_type = 0 requires setting of albedo /= 9999999.9'	The choice of a user-defined albedo requires manual setting of the albedo as there is no default value set.
PA0411	radiation_scheme = "rrtmg" in combination with albedo_type = 0 requires setting of albedo_lw_dif /= 9999999.9, albedo_lw_dir /= 9999999.9, albedo_sw_dif /= 9999999.9 and albedo_sw_dir /= 9999999.9	The choice of a user-defined albedo requires manual setting of all four albedos for direct/diffuse longwave/shortwave radiation as there is no default value set.
PA0412	radiation_scheme = "rrtmg" requires the use of NetCDF (preprocessor directive -Dnetcdf'	The RRTMG library reads atmospheric profiles unsing NetCDF by default. Therefore NetCDf must be activated when using RRTMG.
PA0413	data_output_pr = "..." is not avalable for radiation = .FALSE. or radiation_scheme /= "rrtmg"	Radiative heating rates are only available when using the full RRTMG radiation scheme.

PA0419	mismatch between root model and client settings <parameter name>(root) = ... <parameter name>(client) = ... client value is set to root value	The displayed parameter has been assigned different values for the root domain and a client domain (the id of the client domain is listed in the first line of the message) but it must have the same value for all domains. PALM automatically adjusts the client domain value to the one given for the root domain. In order to get rid of this warning message, adjust the parameter in the respective NAMELIST-parameter file of the client (or root) domain.
PA0420	unknown collision algorithm: collision_algorithm = ...	The only allowed collision algorithms are 'all_or_nothing' and 'average_impact'. Make sure the spelling is correct.
PA0421	recycling_yshift = .T. requires more than one processor in y direction	The distance of the y-shift is calculated by INT( npey / 2 ). With only one processor in y direction, no y-shift is possible.

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.
