| 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 initialization of a cartesian grid. The other shows the |

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

C can be fitted into this design. In this case custom metric terms |

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: |

C o Schemes which leave out blocks of the domain that are |
| 66 |

C all land could be supported. |

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. |
