03318334e8 Jean*0009 C     | The design here supports a three-dimensional model grid

                0011 C     | is comprised of nPx*nSx blocks (or tiles) of size sNx
                0012 C     | along the first (left-most index) axis, nPy*nSy blocks
                0013 C     | of size sNy along the second axis and one block of size
                0014 C     | Nr along the vertical (third) axis.
                0015 C     | Blocks/tiles have overlap regions of size OLx and OLy
                0016 C     | along the dimensions that are subdivided.
