Abstract

Summary Weproposea two-level preconditioning strategy for the iterative solution of large sparse linear systems arising from a discontinuous Galerkin discretization of the radiation diffusion equations. The idea is to usea continuous finite element discretization of theoriginal, elliptic diffusion equation for preconditioning the discontinuous equations. We show how our preconditioner is developed and applied to radiation diffusion problems on unstructured, tetrahedral meshes. We present numerical results to illustrate its effectiveness.
