Comparison of coupled solvers for FEM/BEM linear systems arising from discretization of aeroacoustic problems

Abstract

When discretization of an aeroacoustic physical model is based on the application of both the Finite Elements Method (FEM) and the Boundary Elements Method (BEM), this leads to coupled FEM/BEM linear systems combining sparse and dense parts. In this work, we propose and compare a set of implementation schemes relying on the coupling of the open-source sparse direct solver MUMPS with the proprietary direct solvers from Airbus Central R&T, i.e. the scalapack-like dense solver SPIDO and the hierarchical H-matrix compressed solver HMAT. For this preliminary study, we limit ourselves to a single 24-core computational node.
