The Black-Box Multigrid Methodalso show how the method should be modified for a most difficult problem arising from the finite-volume discretization of a diffusion problem with discontinuous coefficients. The method can be easily extended to uniform cubic grids and coefficient matrices with 27-point stencil.

Matrix-Based Multigrid for Locally Refined Meshesficients to the PDE and the meshsize. Although the diagonaldominance assumptions are rather strong, they are nevertheless satisfied in the present numerical examples that illustrate the usefulness of the method for standard and parallelizable multigrid cycles.
