Bugfix: i_omp_start changed for advec_u_ws at left inflow and outflow boundary. ! This ensures that left-hand side fluxes are also calculated for nxl in that ! case, even though the solution at nxl is overwritten in boundary_conds() ! ! 1398 2014-05-07 11:15:00Z heinze ! Rayleigh-damping for horizontal velocity components changed: instead of damping ! against ug and vg, damping against u_init and v_init is used to allow for a ! homogenized treatment in case of nudging ! ! 1380 2014-04-28 12:40:45Z heinze !

Additionally, it is allowed to call the microphysics just once during the time ! step (not at each sub-time step). ! !
