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