On the energetic Galerkin boundary element method applied to interior wave propagation problems

Abstract

We consider two-dimensional interior wave propagation problems with vanishing initial and mixed boundary conditions, reformulated as a system of two boundary integral equations with retarded potential. These latter are then set in a weak form, based on a natural energy identity satisfied by the solution of the differential problem, and discretized by the related energetic Galerkin boundary element method. Numerical results are presented and discussed. © 2009 Elsevier B.V. All rights reserved.
