hypre_obj_BuildMatrixS Subroutine

private subroutine hypre_obj_BuildMatrixS(this)

Define the entries of the matrix Ax=b one row at a time Finite difference/Finite volume 2nd order Laplacian: ddu/dxdx = -2 u(i,j,k)/dxdx + u(i-1,j,k)/dxdx + u(i+1,j,k)/dxdx ddu/dydy = -2 u(i,j,k)/dydy + u(i,j-1,k)/dydy + u(i,j+1,k)/dydy ddu/dzdz = -2 u(i,j,k)/dzdz + u(i,j,k-1)/dzdz + u(i,j,k+1)/dzdz
