C SUBROUTINE FLT_INIT_VARIA |
| 10 |
C ================================================================== |
| 11 |
C o This routine initializes the start/restart positions. |
| 12 |
C o Either read initial position from file "flt_file" or |
| 13 |
C read pickup file. The 2 type of files are similar, except |
| 14 |
C initial positions are given on grid-coordinate (distance/degree |
| 15 |
C depending on the grid) whereas in pickup file, positions are |
| 16 |
C fractional indices along the grid and local to the tile. |
| 17 |
C For this reason global pickup file is not supported. |
| 18 |
C Initialisation: |
| 19 |
C o First it check for global file, and when found, reads the global file |
| 20 |
C (that has the same format as local files) and sorts those floats |
| 21 |
C that exist on the specific tile into the local array. |
| 22 |
C o If no global file is available or in a case of a restart (pickup |
| 23 |
C file from a previous integration) then read tiled file without |
| 24 |
C any further check (because they exist on the specific tile). |
