304 | !!jc1: For agrif, it would be much better to finalize tracers/momentum here (e.g. bdy conditions) and move the swap |
---|
305 | !! (and time filtering) after Agrif update. Then restart would be done after and would contain updated fields. |
---|
306 | !! If so: |
---|
307 | !! (i) no need to call agrif update at initialization time |
---|
308 | !! (ii) no need to update "before" fields |
---|
309 | !! |
---|
310 | !! Apart from creating new tra_swp/dyn_swp routines, this however: |
---|
311 | !! (i) makes boundary conditions at initialization time computed from updated fields which is not the case between |
---|
312 | !! two restarts => restartability issue. One can circumvent this, maybe, by assuming "interface separation", |
---|
313 | !! e.g. a shift of the feedback interface inside child domain. |
