This revision includes a quite large number of new features, changes and bugfixes.<br> <br>Particle reflection from vertical walls implemented. The particle SGS model is also adjusted to these vertical walls.<br><br>Wall functions for vertical walls now include diabatic conditions. New subroutines <span style="font-family: Courier New,Courier,monospace;">wall_fluxes</span>, <span style="font-family: Courier New,Courier,monospace;">wall_fluxes_e</span>.

The time interval on which the precipitation amount is defined is set by new d3par-parameter <span style="font-family: Courier New,Courier,monospace;">precipitation_amount_interval</span>.<br><br>New inipar-parameter <span style="font-family: Courier New,Courier,monospace;">loop_optimization</span> to control the loop optimization method.<br><br>New 2272 inipar-parameter <span style="font-family: Courier New,Courier,monospace;">pt_reference</span>. If given, this value is used as the 2273 reference that is used in the buoyancy terms (otherwise, the instantaneous 2274 horizontally averaged temperature is used).<br><br>New d3par-parameter <span style="font-family: Courier New,Courier,monospace;">netcdf_64bit_3d</span> 2275 to switch on and especially to switch off 64bit offset for 3D 2276 files only (because still some pd-software is unable to handle 64bit 2277 offset).<br><br>New d3par-parameter <span style="font-family: Courier New,Courier,monospace;">dt_max</span> to set the maximum value allowed for the timestep. <br><br>New user interfaces <span style="font-family: Courier New,Courier,monospace;">user_advec_particles</span> and <span style="font-family: Courier New,Courier,monospace;">user_init_3d_model</span>.

The calculation of a mean outflow is not needed any more. Volume flow control is added for the outflow boundary (<span style="font-weight: bold;">currently only for the north boundary!!</span>). Additional gridpoints along x and y (<span style="font-family: Courier New,Courier,monospace;">uxrp</span>, <span style="font-family: Courier New,Courier,monospace;">vynp</span>) are not needed any more and removed from the code. Routine "<span style="font-family: Courier New,Courier,monospace;">boundary_conds</span>" now operates on timelevel <span style="font-family: Courier New,Courier,monospace;">t+dt</span> and is not split in two parts (<span style="font-style: italic;">main</span>, <span style="font-style: italic;">uvw_outflow</span>) any more. Neumann boundary conditions are used at inflow/outflow in case of non-cyclic boundary conditions <span style="font-weight: bold;">for all 2d-arrays</span> that are handled by <span style="font-family: Courier New,Courier,monospace;">exchange_horiz_2d</span>.<br><span style="font-weight: bold;">Attention: the 2284 non-cyclic boundary conditions of this revision still contain some bugs 2285 which will be removed within the next revisions!</span><br><br>The Bott-Chlond-scheme can now be used in the vectorization-optimized part (NEC, etc.). Equations are solved up to gridpoint <span style="font-family: Courier New,Courier,monospace;">nzt</span>.<br><br>The 2286 FFT-method for solving the Poisson-equation is now working with Neumann 2287 boundary conditions both at the bottom and the top. This requires 2288 adjustments of the tridiagonal coefficients and subtracting the 2289 horizontally averaged mean from the vertical velocity field.<br><br>Particles-package is now part of the default code ("<span style="font-family: Courier New,Courier,monospace;">-p particles</span>" is not needed as an <span style="font-weight: bold;">mrun</span>-option any more). New attribute <span style="font-family: Courier New,Courier,monospace;">age_m</span> in <span style="font-family: Courier New,Courier,monospace;">particle_type</span>.<br><br>Move call of <span style="font-family: Courier New,Courier,monospace;">user_actions</span>( '<span style="font-style: italic;">after_integration</span>' ) below the increments of times<br>and counters. <span style="font-family: Courier New,Courier,monospace;">user_actions</span> is now called for each statistic region and has as an argument the number of the respective region (<span style="font-family: Courier New,Courier,monospace;">sr</span>).<br><br>d3par-parameter <span style="font-family: Courier New,Courier,monospace;">data_output_ts</span> is removed. Timeseries output for <span style="font-weight: bold;">profil</span>-software removed. Timeseries are now switched on by setting <span style="font-family: Courier New,Courier,monospace;">dt_dots</span>. Timeseries data is collected in <span style="font-family: Courier New,Courier,monospace;">flow_statistics</span>.<br><br>Initial velocities at <span style="font-family: Courier New,Courier,monospace;">nzb+1</span> 2290 are regarded for volume flow control in case they have been set zero 2291 before (to avoid small timesteps); see new internal parameters <span style="font-family: Courier New,Courier,monospace;">u/v_nzb_p1_for_vfc</span>.<br><br><span style="font-family: Courier New,Courier,monospace;">q</span> is not allowed any more to become negative (<span style="font-family: Courier New,Courier,monospace;">prognostic_equations</span>).<br><br><span style="font-family: Courier New,Courier,monospace;">poisfft_init</span> is only called if the fft-solver is switched on (<span style="font-family: Courier New,Courier,monospace;">init_pegrid</span>).<br><br>d3par-parameter <span style="font-family: Courier New,Courier,monospace;">moisture</span> renamed to <span style="font-family: Courier New,Courier,monospace;">humidity</span>.<br><br>Subversion global revision number is read from <span style="font-weight: bold;">mrun</span> and added to the run description header and to the run control (<span style="font-family: Courier New,Courier,monospace;">_rc</span>) file.<br><br><span style="font-family: Courier New,Courier,monospace;">__vtk</span> directives removed from main program.<br><br>The uitility routine <span style="font-family: Courier New,Courier,monospace;">interpret_config</span> now reads PALM environment variables from <span style="font-family: Courier New,Courier,monospace;">NAMELIST</span> instead using the system call <span style="font-family: Courier New,Courier,monospace;">GETENV</span>.</td><td style="vertical-align: top;">advec_s_bc, advec_u_pw, 2292 advec_u_up, advec_v_pw, advec_v_up, asselin_filter, boundary_conds, check_parameters, 2293 coriolis, data_output_dvrp, data_output_ptseries, data_output_ts, 2294 data_output_2d, data_output_3d, diffusion_u, diffusion_v, 2295 disturb_field, exchange_horiz, exchange_horiz_2d, flow_statistics, header, init_grid, 2296 init_particles, init_pegrid, init_rankine, init_pt_anomaly, 2297 init_1d_model, init_3d_model, modules, palm, package_parin, parin, 2298 poisfft, poismg, prandtl_fluxes, pres, production_e, 2299 prognostic_equations, read_var_list, read_3d_binary, sor, 2300 swap_timelevel, time_integration, write_var_list, write_3d_binary</td></tr><tr><td style="vertical-align: top;"> </td><td style="vertical-align: top;"> </td><td style="vertical-align: top;"> </td><td style="vertical-align: top;">E</td><td style="vertical-align: top;">Bugfix: preset of tendencies <span style="font-family: Courier New,Courier,monospace;">te_em</span>, <span style="font-family: Courier New,Courier,monospace;">te_um</span>, and <span style="font-family: Courier New,Courier,monospace;">te_vm</span> (<span style="font-family: Courier New,Courier,monospace;">init_1d_model</span>).<br><br>Bugfix in sample for reading user defined data from restart file (<span style="font-family: Courier New,Courier,monospace;">user_init</span>).<br><br>Bugfix in setting diffusivities for cases with the outflow damping layer extending over more than one subdomain (<span style="font-family: Courier New,Courier,monospace;">init_3d_model</span>).<br><br>Check for possible negative humidities in the initial humidity profile.<br><br>In <span style="font-family: Courier New,Courier,monospace;">Makefile</span>, default suffixes are removed from the suffix list to avoid calling of <span style="font-family: Courier New,Courier,monospace;">m2c</span> in cases of existing <span style="font-family: Courier New,Courier,monospace;">.mod</span> files (problem on Linux systems).</td><td style="vertical-align: top;">Makefile<br><br>check_parameters, init_1d_model, init_3d_model, user_interface</td></tr> 2273 2301 </tbody> 2274 2302 </table> <b><blink>Attention:</blink></b>
