C sNx - No. X points in sub-grid. C sNy - No. Y points in sub-grid. C OLx - Overlap extent in X. C OLy - Overlat extent in Y. C nSx - No. sub-grids in X. C nSy - No. sub-grids in Y. C nPx - No. of processes to use in X. C nPy - No. of processes to use in Y. C Nx - No. points in X for the total domain. C Ny - No. points in Y for the total domain.
