|
C | SUBROUTINE INI_GRID |
| 13 |
|
|
C | o Initialise model grid |
| 14 |
|
|
C *==========================================================* |
| 15 |
|
|
C | These arrays are used throughout the code in evaluating |
| 16 |
|
|
C | gradients, integrals and spatial avarages. This routine |
| 17 |
|
|
C | is called separately by each thread and initialise only |
| 18 |
|
|
C | the region of the domain it is "responsible" for. |
| 19 |
|
|
C | Notes: |
| 20 |
|
|
C | Two examples are shown in this code. One illustrates the |
| 21 |
|
|
C | initialisation of a cartesian grid. The other shows the |
| 22 |
|
|
C | inialisation of a spherical polar grid. Other orthonormal |
| 23 |
|
|
C | grids can be fitted into this design. In this case |
| 24 |
|
|
C | custom metric terms also need adding to account for the |
| 25 |
|
|
C | projections of velocity vectors onto these grids. |
| 26 |
|
|
C | The structure used here also makes it possible to |
| 27 |
|
|
C | implement less regular grid mappings. In particular |
| 28 |
|
|
C | o Schemes which leave out blocks of the domain that are |
| 29 |
|
|
C | all land could be supported. |
| 30 |
|
|
C | o Multi-level schemes such as icosohedral or cubic |
| 31 |
|
|
C | grid projectedions onto a sphere can also be fitted |
| 32 |
|
|
C | within the strategy we use. |
| 33 |
|
|
C | Both of the above also require modifying the support |
| 34 |
|
|
C | routines that map computational blocks to simulation |
| 35 |
|
|
C | domain blocks. |
