Abstract
The robustness of a non-standard multigrid method called Multiple Semi -coarsened Grids (MSD) is investigated. The smoother is a damped point -Jacobi relaxation method. Three different coarse grid correction stra tegies are implemented and compared. Robustness is investigated by sol ving the rotated anisotropic diffusion equation and the convection dif fusion equation.
