 C     | gradients, integrals and spatial avarages. This routine  |  
 C     | is called separately by each thread and initialise only  |  
 C     | the region of the domain it is "responsible" for.        |  
 C     | Notes:                                                   |  
 C     | Two examples are shown in this code. One illustrates the |  
 C     | initialisation of a cartesian grid. The other shows the  |  
 C     | inialisation of a spherical polar grid. Other orthonormal|  
 C     | grids can be fitted into this design. In this case       |  
 C     | custom metric terms also need adding to account for the  |  
 C     | projections of velocity vectors onto these grids.        |  
 C     | The structure used here also makes it possible to        |  
 C     | implement less regular grid mappings. In particular      |  
 C     | o Schemes which leave out blocks of the domain that are  |  
 C     |   all land could be supported.                           |  
 C     | o Multi-level schemes such as icosohedral or cubic       |  
 C     |   grid projectedions onto a sphere can also be fitted    |  
 C     |   within the strategy we use.                            |  
 C     |   Both of the above also require modifying the support   |  
 C     |   routines that map computational blocks to simulation   |
