A note on the discrete Unmapped Tent Pitching for the heterogeneous wave equation
Marcella Bonazzoli, Gabriele Ciaramella, Ilario Mazzieri
The Unmapped Tent Pitching (UTP) algorithm is a space-time domain decomposition method for the parallel solution of wave-type problems. We have recently extended UTP to heterogeneo…
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…
