C *==========================================================* |
| 14 |
C | SUBROUTINE INITIALISE_FIXED |
| 15 |
C | o Routine for setting fixed model arrays such as |
| 16 |
C | topography, grid, solver matrices, etc. |
| 17 |
C *==========================================================* |
| 18 |
C | INITIALISE_FIXED is invoked at the start of the model to |
| 19 |
C | set fixed model arrays. It reads data from an input file |
| 20 |
C | and from various binary files. |
| 21 |
C | Each thread invokes an instance of this routine as does |
| 22 |
C | each process in a multi-process parallel environment like |
| 23 |
C | MPI. |
