r4110 r4117 21 21 ! Current revisions: 22 22 ! ----------------- 23 ! 23 ! - When Dirichlet condition is applied in decycling, the boundary conditions are 24 ! only set at the ghost points and not at the prognostic grid points as done 25 ! before 26 ! - Rename decycle_ns/lr to decycle_salsa_ns/lr and decycle_method to 27 ! decycle_method_salsa 28 ! - Allocation and initialization of special advection flags salsa_advc_flags_s 29 ! used for salsa. These are exclusively used for salsa variables to 30 ! distinguish from the usually-used flags which might be different when 31 ! decycling is applied in combination with cyclic boundary conditions. 32 ! Moreover, salsa_advc_flags_s considers extended zones around buildings where 33 ! the first-order upwind scheme is applied for the horizontal advection terms. 34 ! This is doneto overcome high concentration peaks due to stationary numerical 35 ! oscillations caused by horizontal advection discretization. 24 36 ! 25 37 !
