C | The design here support a three-dimensional model grid | |
7 |
C | with indices I,J and K. The three-dimensional domain | |
8 |
C | is comprised of nPx*nSx blocks of size sNx along one axis| |
9 |
C | nPy*nSy blocks of size sNy along another axis and one | |
10 |
C | block of size Nz along the final axis. | |
11 |
C | Blocks have overlap regions of size OLx and OLy along the| |
12 |
C | dimensions that are subdivided. | |
