C o This routine initializes the start/restart positions. |
| 13 |
C It does the following: |
| 14 |
C o First it checks for local files. These are supposed to be restarts |
| 15 |
C from a previous integration. The floats can therefore be read in |
| 16 |
C without any further check (because they exist on the specific tile). |
| 17 |
C o If no local files are available the routine assumes that this |
| 18 |
C is an initialization. In that case it reads a global file |
| 19 |
C (that has the same format as local files) and sorts those floats |
| 20 |
C that exist on the specific tile into the local array. |
| 21 |
C o At the end the float positions are written to the trajectory file |
