A fully discrete BEM-FEM scheme for transient acoustic waves
Matthew E. Hassell, Francisco-Javier Sayas
We study a symmetric BEM-FEM coupling scheme for the scattering of transient acoustic waves by bounded inhomogeneous anisotropic obstacles in a homogeneous field. An incident wave…
A new and improved analysis of the time domain boundary integral operators for acoustics
Matthew Hassell, Tianyu Qiu, Tonatiuh Sanchez-Vizuet +1
We present a novel analysis of the boundary integral operators associated to the wave equation. The analysis is done entirely in the time-domain by employing tools from abstract ev…
Boundary integral solvers for an evolutionary exterior Stokes problem
Constantin Bacuta, Matthew E. Hassell, George C. Hsiao +1
This paper proposes and analyzes a full discretization of the exterior transient Stokes problem with Dirichlet boundary conditions. The method is based on a single layer boundary i…
Convolution Quadrature for Wave Simulations
Matthew Hassell, Francisco-Javier Sayas
These notes build an introduction to Convolution Quadrature techniques applied to linear convolutions and convolution equations with a bias to problems related to wave propagation.…
