C | SUBROUTINE INI_NH_FIELDS |
| 14 |
C | o Set model initial non-hydrostatic fields. |

C *==========================================================* |
| 16 |
C | Note: If using NH form, |
| 17 |
C | call this S/R whether starting or restarting simulation. |
| 18 |
C | This is different from other "true" ini_fields type S/R |
| 19 |
C | (e.g., INI_VEL) which are called only when starting. |
| 20 |
C | Reason: no real physical field to initialise (since wVel |
| 21 |
C | is diagnose from continuity) but needs to set few arrays |
