| [5930] | 269 | !!jc1: For agrif, it would be much better to finalize tracers/momentum here (e.g. bdy conditions) and move the swap |
|---|
| 270 | !! (and time filtering) after Agrif update. Then restart would be done after and would contain updated fields. |
|---|
| 271 | !! If so: |
|---|
| 272 | !! (i) no need to call agrif update at initialization time |
|---|
| 273 | !! (ii) no need to update "before" fields |
|---|

|---|
| 275 | !! Apart from creating new tra_swp/dyn_swp routines, this however: |
|---|
| 276 | !! (i) makes boundary conditions at initialization time computed from updated fields which is not the case between |

|---|
| 278 | !! e.g. a shift of the feedback interface inside child domain. |
