MULTIGRID AND CYCLIC REDUCTION APPLIED TO THE HELMHOLTZ EQUATION N 94 - 2 S 676 Kenneth

  • Kenneth Brackenrldge

Abstract

We consider the Helmholtz equation with a discontinuous complex parameter and inhomogeneous Dirichlet boundary conditions in a rectangular domain. A variant of the direct method of cyclic reduction is employed to facilitate the design of improved multigrid components, resulting in the method of CR-MG. We demonstrate the improved convergence properties of this method.
