Coarse space preconditioning for Generalized Optimized Schwarz Methods. Part I: continuous case
Xavier Claeys
The Generalized Optimized Schwarz Method (GOSM) originally proposed in [Claeys, 2021] is a variant of Deprés algorithm, a domain decomposition strategy for the solution of harmonic…
Multi-domain FEM-BEM coupling with several impenetrable obstacles
Antonin Boisneault, Marcella Bonazzoli, Xavier Claeys +1
In a recent paper we have analyzed a new formulation of the coupling of finite and boundary element methods (FEM-BEM) for Helmholtz problems, involving several heterogeneous bounde…
Discrete FEM-BEM coupling with the Generalized Optimized Schwarz Method
Antonin Boisneault, Marcella Bonazzoli, Xavier Claeys +1
The present contribution aims at developing a non-overlapping Domain Decomposition (DD) approach to the solution of acoustic wave propagation boundary value problems based on the H…
Spurious resonances for substructured FEM-BEM coupling
Antonin Boisneault, Marcella Bonazzoli, Pierre Marchand +1
We are interested in time-harmonic acoustic scattering by an impenetrable obstacle in a medium where the wavenumber is constant in an exterior unbounded subdomain and is possibly h…
