Unstructured volume-agglomeration MG : solution of the Poisson equation

Abstract

We are interested in solving second-order PDE's with multigrid and unstructured meshes. The multigrid strategy we present here is adapted from the generalized finite volume agglomeration multigrid algorithm we have developed recently for the solution of the Euler equations. We now focus on the Poisson's equation. A strategy is defined by introducing a correction factor for the diffusive terms and some illustrating results are given.
