C | SUBROUTINE INI_GRID | |
| 10 |
C | o Initialise model grid | |
| 11 |
C |==========================================================| |
| 12 |
C | These arrays are used throughout the code in evaluating | |
| 13 |
C | gradients, integrals and spatial avarages. This routine | |
| 14 |
C | is called separately by each thread and initialise only | |
| 15 |
C | the region of the domain it is "responsible" for. | |
| 16 |
C | Notes: | |
| 17 |
C | Two examples are shown in this code. One illustrates the | |
| 18 |
C | initialisation of a cartesian grid. The other shows the | |
| 19 |
C | inialisation of a spherical polar grid. Other orthonormal| |
| 20 |
C | grids can be fitted into this design. In this case | |
| 21 |
C | custom metric terms also need adding to account for the | |
| 22 |
C | projections of velocity vectors onto these grids. | |
| 23 |
C | The structure used here also makes it possible to | |
| 24 |
C | implement less regular grid mappings. In particular | |
| 25 |
C | o Schemes which leave out blocks of the domain that are | |
| 26 |
C | all land could be supported. | |
| 27 |
C | o Multi-level schemes such as icosohedral or cubic | |
| 28 |
C | grid projectedions onto a sphere can also be fitted | |
| 29 |
C | within the strategy we use. | |
| 30 |
C | Both of the above also require modifying the support | |
| 31 |
C | routines that map computational blocks to simulation | |
| 32 |
C | domain blocks. | |
