Discretization in Multilayered Media with High Contrasts: Is It All About the Boundaries?
Camille Carvalho, Stéphanie Chaillat, Elsie Cortes +1
Wave propagation in multilayered media with high material contrasts poses significant numerical challenges, as large variations in wavenumbers lead to strong reflections and comple…
Theory and implementation of -matrix based iterative and direct solvers for Helmholtz and elastodynamic oscillatory kernels
Stéphanie Chaillat, Luca Desiderio, Patrick Ciarlet
In this work, we study the accuracy and efficiency of hierarchical matrix (-matrix) based fast methods for solving dense linear systems arising from the discretization…
Seismic Wave Amplification in 3D Alluvial Basins: 3D/1D Amplification Ratios from Fast Multipole BEM Simulations
Kristel C Meza Fajardo, Jean-François Semblat, Stéphanie Chaillat +1
In this work, we study seismic wave amplification in alluvial basins having 3D standard geometries through the Fast Multipole Boundary Element Method in the frequency domain. We in…
