New: --- Allows runs for a coupled atmosphere-ocean LES, coupling frequency is controlled by new d3par-parameter dt_coupling, the coupling mode (atmosphere_to_ocean or ocean_to_atmosphere) for the respective processes is read from environment variable coupling_mode, which is set by the mpiexec-command, communication between the two models is done using the intercommunicator comm_inter, local files opened by the ocean model get the additional suffic "_O" A momentum flux can be set as top boundary condition using the new inipar parameter top_momentumflux_u|v. boundary_conds, check_open, check_parameters, diffusion_u, diffusion_v, flow_statistics, header, init_pegrid, init_3d_model, modules, palm, parin, prognostic_equations, read_var_list, read_3d_binary, swap_timelevel, time_integration, write_var_list, write_3d_binary New: surface_coupler Changed: ------- Errors: ------ Bugfix: Error message concerning output of particle concentration (pc) modified (check_parameters). check_parameters
