Analysis and application of an overlapped FEM-BEM for wave propagation in unbounded and heterogeneous media
An overlapped continuous model framework, for the Helmholtz wave propagation problem in unbounded regions comprising bounded heterogeneous media, was recently introduced and analyzed by the authors (2020) [10]. The continuous ... -
Boundary integral equation methods for the solution of scattering and transmission 2D elastodynamic problems
We introduce and analyse various regularized combined field integral equations (CFIER) formulations of time-harmonic Navier equations in media with piece-wise constant material properties. These formulations can be derived ... -
A fully discrete Calderón calculus for the two-dimensional elastic wave equation
In this paper we present a full discretization of the layer potentials and boundary integral operators for the elastic wave equation on a parametrizable smooth closed curve in the plane. The method can be understood as a ... -
High order Nyström methods for transmission problems for Helmholtz equation
We present super-algebraic compatible Nyström discretizations for the four Helmholtz boundary operators of Calderón’s calculus on smooth closed curves in 2D. These discretizations are based on appropriate splitting of the ... -
Nyström discretizations of boundary integral equations for the solution of 2D elastic scattering problems
(Elsevier, 2024) Artículo / ArtikuluaWe present three high-order Nyström discretization strategies of various boundary integral equation formulations of the impenetrable time-harmonic Navier equations in two dimensions. One class of such formulations is ... -
An overlapping decomposition framework for wave propagation in heterogeneous and unbounded media: formulation, analysis, algorithm, and simulation
A natural medium for wave propagation comprises a coupled bounded heterogeneous region and an unbounded homogeneous free-space. Frequency-domain wave propagation models in the medium, such as the variable coefficient ...
