A fully discrete Calderón calculus for the two-dimensional elastic wave equation
Domínguez Baguena, Víctor ; Sánchez Vizuet, Tonatiuh; Sayas, Francisco Javier (Elsevier, 2015) Artículo / ArtikuluaIn 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 ... -
A mixed-FEM and BEM coupling for the approximation of the scattering of thermal waves in locally non-homogeneous media
This paper proposes and analyzes a BEM-FEM scheme to approximate a time-harmonic diffusion problem in the plane with non-constant coefficients in a bounded area. The model is set as a Helmholtz transmission problem with ... -
An overlapping decomposition framework for wave propagation in heterogeneous and unbounded media: formulation, analysis, algorithm, and simulation
Domínguez Baguena, Víctor ; Ganesh, M.; Sayas, Francisco Javier (Elsevier, 2020) Artículo / ArtikuluaA 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 ...
