New:

Plant canopy model of Watanabe (2004,BLM 112,307-341) added.
It can be switched on by the inipar parameter plant_canopy.
The inipar parameter canopy_mode can be used to prescribe a
plant canopy type. The default case is a homogeneous plant
canopy. Heterogeneous distributions of the leaf area
density and the canopy drag coefficient can be defined in the
new routine user_init_plant_canopy (user_interface).
The inipar parameters lad_surface, lad_vertical_gradient and
lad_vertical_gradient_level can be used in order to
prescribe the vertical profile of leaf area density. The
inipar parameter drag_coefficient determines the canopy
drag coefficient.
Finally, the inipar parameter pch_index determines the
index of the upper boundary of the plant canopy.

Allow new case bc_uv_t = 'dirichlet_0' for channel flow.

For unknown variables (CASE DEFAULT) call new subroutine user_data_output_dvrp

Pressure boundary conditions for vertical walls added to the multigrid solver.
They are applied using new wall flag arrays (wall_flags_..) which are defined
for each grid level. New argument gls added to routine user_init_grid
(user_interface).

Frequence of sorting particles can be controlled with new particles_par
parameter dt_sort_particles. Sorting is moved from the SGS timestep loop in
advec_particles after the end of this loop.

Changed:


Redefine initial nzb_local as the actual total size of topography (later the
extent of topography in nzb_local is reduced by 1dx at the E topography walls
and by 1dy at the N topography walls to form the basis for nzb_s_inner);
for consistency redefine 'single_building' case.

Vertical profiles now based on nzb_s_inner; they are divided by
ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered velocity
components and their products, procucts of scalars and velocity components),
respectively.

Allow two instead of one digit to specify isosurface and slicer variables.

Status of 3D-volume NetCDF data file only depends on switch netcdf_64bit_3d (check_open)

prognostic_equations include the respective wall_*flux in the parameter list of
calls of diffusion_s. Same as before, only the values of wall_heatflux(0:4)
can be assigned. At present, wall_humidityflux, wall_qflux, wall_salinityflux,
and wall_scalarflux are kept zero. diffusion_s uses the respective wall_*flux
instead of wall_heatflux. This update serves two purposes:

  • it avoids errors in calculations with humidity/scalar/salinity and prescribed

non-zero wall_heatflux,

  • it prepares PALM for a possible assignment of wall fluxes of

humidity/scalar/salinity in a future release.

Errors:


Bugfix: summation of sums_l_l in diffusivities.

Several bugfixes in the ocean part: Initial density rho is calculated
(init_ocean). Error in initializing u_init and v_init removed
(check_parameters). Calculation of density flux now starts from
nzb+1 (production_e).

Bugfix: pleft/pright changed to pnorth/psouth in sendrecv of particle tail
numbers along y, small bugfixes in the SGS part (advec_particles)

Bugfix: model_string needed a default value (combine_plot_fields)

Bugfix: wavenumber calculation for even nx in routines maketri (poisfft)

Bugfix: assignment of fluxes at walls

Bugfix: absolute value of f must be used when calculating the Blackadar mixing length (init_1d_model)
