C | The design here support a three-dimensional model grid |
| 12 |
|
|
C | with indices I,J and K. The three-dimensional domain |
| 13 |
|
|
C | is comprised of nPx*nSx blocks of size sNx along one axis |
| 14 |
|
|
C | nPy*nSy blocks of size sNy along another axis and one |
| 15 |
|
|
C | block of size Nz along the final axis. |
| 16 |
|
|
C | Blocks have overlap regions of size OLx and OLy along the |
| 17 |
|
|
C | dimensions that are subdivided. |
