C | SUBROUTINE INI_CURVILINEAR_GRID |
| 13 |
C | o Initialise curvilinear coordinate system |
| 14 |
C *==========================================================* |
| 15 |
C | Curvilinear grid settings are read from a file rather |
| 16 |
C | than coded in-line as for cartesian and spherical polar. |
| 17 |
C | This is more general but you have to create the grid |
| 18 |
C | yourself. |
