Robust Hierarchical Matrix Compression of Acoustic Volume and Boundary Integral Operators
Alberto Almuna-Morales, Danilo Aballay, Ignacio Labarca-Figueroa +1
Discretizing integral formulations of the Helmholtz equation yields dense linear systems. Hence, simulating acoustic models at larger scales or higher frequencies is typically cons…
Nested Volume-Surface Integral Equations for Acoustics
Danilo Aballay, Elwin van 't Wout
The simulation of high-frequency acoustic wave propagation in unbounded domains with local heterogeneous materials and high-contrast interfaces poses significant challenges to nume…
The Boundary Element Method for Acoustic Transmission with Nonconforming Grids
Elwin van 't Wout
Acoustic wave propagation through a homogeneous material embedded in an unbounded medium can be formulated as a boundary integral equation and accurately solved with the boundary e…
Stable and efficient FEM-BEM coupling with OSRC regularisation for acoustic wave transmission
Elwin van 't Wout
The finite element method (FEM) and the boundary element method (BEM) can numerically solve the Helmholtz system for acoustic wave propagation. When an object with heterogeneous wa…
Frequency-robust preconditioning of boundary integral equations for acoustic transmission
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The scattering and transmission of harmonic acoustic waves at a penetrable material are commonly modelled by a set of Helmholtz equations. This system of partial differential equat…
