C These arrays are used throughout the code in evaluating gradients, |

C integrals and spatial avarages. This routine is called separately |
| 15 |

|
C by each thread and initializes only the region of the domain it is |

C Two examples are shown in this code. One illustrates the |

C inialization of a spherical polar grid. Other orthonormal grids |

|
C can be fitted into this design. In this case custom metric terms |
| 62 |
|
|
C also need adding to account for the projections of velocity |
| 63 |
|
|
C vectors onto these grids. The structure used here also makes it |
| 64 |
|
|
C possible to implement less regular grid mappings. In particular: |
| 65 |
|
|
C o Schemes which leave out blocks of the domain that are |
| 66 |
|
|
C all land could be supported. |
| 67 |
|
|
C o Multi-level schemes such as icosohedral or cubic |
| 68 |
|
|
C grid projectedions onto a sphere can also be fitted |
| 69 |
|
|
C within the strategy we use. |
| 70 |
|
|
C Both of the above also require modifying the support |
