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 preliminary study, we compare a set of sparse and dense solvers applied on the solution of such type of linear systems with the aim to identify the best performing configurations of existing solvers.
