C  The design here support a threedimensional model grid  
9 
C  with indices I,J and K. The threedimensional domain  
10 
C  is comprised of nPx*nSx blocks of size sNx along one axis 
11 
C  nPy*nSy blocks of size sNy along another axis and one  
12 
C  block of size Nz along the final axis.  
13 
C  Blocks have overlap regions of size OLx and OLy along the 
14 
C  dimensions that are subdivided.
