The improved robustness of multigrid elliptic solvers based on multiple semicoarsened grids [PDF]

Multigrid convergence rates degenerate on problems with stretched grids or anisotropic operators, unless one uses line or plane relaxation. For 3-D problems, only plane relaxation suffices, in general.

NUMERICAL SOLUTION OF 2-D EULER EQUATIONS WITH MULTIGRID

Havacılık ve Uzay Teknolojileri Dergisi, 2007
A multigrid scheme is applied to accelerate the convergence of numerical solution of two dimensional Euler equations to steady state. Cell-centered finite volume method with central differencing scheme is used for discretization. Explicit multistage time-
