C  The design here support a threedimensional model grid 
14 
C  with indices I,J and K. The threedimensional 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 
C  dimensions that are subdivided.
