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…
Convergence rates of curved boundary element methods for the 3D Laplace and Helmholtz equations
Luiz Maltez Faria, Pierre Marchand, Hadrien Montanelli
We establish improved convergence rates for curved boundary element methods applied to the three-dimensional (3D) Laplace and Helmholtz equations with smooth geometry and data. Our…
