C     | The design here support a three-dimensional model grid   |
C     | with indices I,J and K. The three-dimensional domain     |
C     | is comprised of nPx*nSx blocks of size sNx along one axis|
C     | nPy*nSy blocks of size sNy along another axis and one    |
C     | block of size Nz along the final axis.                   |
C     | Blocks have overlap regions of size OLx and OLy along the|
C     | dimensions that are subdivided.                          |

C     OLx - Overlap extent in X.
C     OLy - Overlat extent in Y.
C     Nx  - No. points in X for the total domain.
C     Ny  - No. points in Y for the total domain.
