Abstract

A comparison of nonlinear and linear p- and h-multigrid algorithms will be presented with respect to both algorithmic convergence properties and run-time behavior. In addition to that a comparison with a single-level solver, namely a Backward--Euler method, will be presented as well. The algorithms will be used to solve the RANS-equations in combination with a k-w turbulence models for CFD applications in the area of compressible aerodynamic fows with high Reynolds numbers. The h-multigrid algorithms are formulated on agglomerated unstructured meshes. Results will be presented on both structured and unstructred meshes.
