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.
