C !DESCRIPTION: |
| 14 |
C----- |
| 15 |
C Called at the beginning of the time-step, |
| 16 |
C to switch on/off diagnostics for snap-shot output |
| 17 |
C----- |
| 18 |
C during iterations that are multiple of |freq|, |
| 19 |
C switch ON diagnostics (ndiag>=0) that will become active |
| 20 |
C and then can be written at the end of the time-step ; |
| 21 |
C otherwise, put diagnostics in non-active mode (ndiag=-1) |
