The paper's leitmotiv is condensed in one word: robustness. This is a real hindrance for the successful implementation of any multigrid scheme for solving the Navier-Stokes set of equations. In this paper, many hints are given to improve this issue. Instead of looking for the best possible speed-up rate for a particular set of problems, at a given regime… (More)
Domain decomposition methods in nite element applied aerodynamics provides a real speed-up of the convergence and good parallel scalability, even with the minimum overlap approach used here. Furthermore, a new variant of Restricted Additive Schwarz procedure is tested and shows a very attractive scalability property.
