Abstract:
We develop a simple semi-algebraic 2-level solver built
on traditional multigrid ideas. It is designed to be easily
incorporated into existing simulation software. It exhibits good
convergence for many classes of challenging problems including
discontinuous diffusion, convection-diffusion, and Helmholtz
equations. It has built-in structure that makes it simple to
generalize to a hierarchical basis multigrid solver,
