C | SUBROUTINE INITIALISE_VARIA |
| 13 |
C | o Set the initial conditions for dynamics variables |

C | This routine reads/writes data from an input file and |
| 17 |
C | from various binary files. |
| 18 |
C | Each thread invokes an instance of this routine as does |
| 19 |
C | each process in a multi-process parallel environment like |
