C | The design here support a three-dimensional model grid |
14 |
|
|
C | with indices I,J and K. The three-dimensional domain |
15 |
|
|
C | is comprised of nPx*nSx blocks of size sNx along one axis |
16 |
|
|
C | nPy*nSy blocks of size sNy along another axis and one |
17 |
|
|
C | block of size Nz along the final axis. |
18 |
|
|
C | Blocks have overlap regions of size OLx and OLy along the |
19 |
