Abstract
A systematic approach is developed for gaining insight into complicate d systems of partial differential equations (PDEs) in order to constru ct efficient smoothers for multigrid solvers. The method is derived fr om local mode (smoothing) analysis and employs algebraic graph theory, but it requires no knowledge of either in its implementation. It is a pplied to several problems, for which finding the best approach withou t such an analysis can be quite challenging.
