Parallel Multigrid for Anisotropic Elliptic Equations
Copyright policy )Parallel Multigrid for Anisotropic Elliptic Equations
Interesting investigations for anisotropy by the cofficients of partial differential equations and by mesh anisotropy, for multigrid with a) alternating plane smoothers combined with standard coarsening and b) plane smoothers with semicoarsening algorithm. While on sequential computers a) is better, b) is better on parallel computers (although with disappointing efficiency).
