Description
Techniques are developed for accelerating multigrid convergence in general, and for advection-diffusion and incompressible flow problems with small viscosity in particular. It is shown by analysis that the slowing down of convergence is due mainly to poor coarse-grid correction to certain error components, and means for dealing with this problem are suggested, analyzed, and tested by numerical experiments, showing very significant improvement in convergence rates at little cost.
