| 283 | !!jc1: For agrif, it would be much better to finalize tracers/momentum here (e.g. bdy conditions) and move the swap |
|---|
| 284 | !! (and time filtering) after Agrif update. Then restart would be done after and would contain updated fields. |
|---|
| 285 | !! If so: |
|---|
| 286 | !! (i) no need to call agrif update at initialization time |
|---|
| 287 | !! (ii) no need to update "before" fields |
|---|
| 288 | !! |
|---|
| 289 | !! Apart from creating new tra_swp/dyn_swp routines, this however: |
|---|
| 290 | !! (i) makes boundary conditions at initialization time computed from updated fields which is not the case between |
|---|
| 291 | !! two restarts => restartability issue. One can circumvent this, maybe, by assuming "interface separation", |
|---|
| 292 | !! e.g. a shift of the feedback interface inside child domain. |
|---|
| 293 | !! (ii) requires that all restart outputs of updated variables by agrif (e.g. passive tracers/tke/barotropic arrays) are done at the same |
|---|
| 294 | !! place. |
