Branch: MAIN

Changes since 1.24: +4 -1 lines
reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
(ini_parms.F is shorter ; allows later to read from netcdf files)

10 C !INTERFACE:
11 SUBROUTINE INI_GRID( myThid )
12 C !DESCRIPTION:
13 C These arrays are used throughout the code in evaluating gradients,
14 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
16 C "responsible" for.

40 C load grid spacing (vector) from files
41 CALL LOAD_GRID_SPACING( myThid )

43 C Set up vertical grid and coordinate system
44 CALL INI_VERTICAL_GRID( myThid )
45
46 C Two examples are shown in this code. One illustrates the
47 C initialization of a cartesian grid. The other shows the
48 C inialization of a spherical polar grid. Other orthonormal grids
49 C can be fitted into this design. In this case custom metric terms
50 C also need adding to account for the projections of velocity
51 C vectors onto these grids. The structure used here also makes it
52 C possible to implement less regular grid mappings. In particular:
53 C o Schemes which leave out blocks of the domain that are
54 C all land could be supported.
55 C o Multi-level schemes such as icosohedral or cubic
56 C grid projectedions onto a sphere can also be fitted
57 C within the strategy we use.
58 C Both of the above also require modifying the support
59 C routines that map computational blocks to simulation
60 C domain blocks.
