[5930] | 275 | !!jc1: For agrif, it would be much better to finalize tracers/momentum here (e.g. bdy conditions) and move the swap |

| 276 | !! (and time filtering) after Agrif update. Then restart would be done after and would contain updated fields. |
---|
| 277 | !! If so: |
---|
| 278 | !! (i) no need to call agrif update at initialization time |
---|
| 279 | !! (ii) no need to update "before" fields |

| 281 | !! Apart from creating new tra_swp/dyn_swp routines, this however: |
