Multiplicative and additive parallel multigrid algorithms for the acceleration of compressible flow computations on unstructured meshes

In this paper we examine how parallel multigrid acceleration can be used to improve the efficiency of two-dimensional compressible steady flow calculations on unstructured meshes. We study two parallel multigrid formulations. The first one is based on the standard approach that relies on domain part...
