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…
Classifying acoustic cavitation with machine learning trained on multiple physical models
Trinidad Gatica, Elwin van 't Wout, Reza Haqshenas
Acoustic cavitation threshold charts are used to map between acoustic parameters (mainly intensity and frequency) and different regimes of acoustic cavitation. The two main regimes…
Modeling Global Surface Dust Deposition Using Physics-Informed Neural Networks
Constanza A. Molina Catricheo, Fabrice Lambert, Julien Salomon +1
Paleoclimatic measurements serve to understand Earth System processes and evaluate climate model performances. However, their spatial coverage is generally sparse and unevenly dist…
Modeling frequency shifts of collective bubble resonances with the boundary element method
Rudyard Jerez Boudesseul, Elwin van 't Wout
Increasing the number of closely-packed air bubbles immersed in water changes the frequency of the Minnaert resonance. The collective interactions between bubbles in a small ensemb…
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…
