Numerical Treatment of Retarded Boundary Integral Equations by Sparse Panel Clustering (extended version)

Wendy Kress and Stefan A. Sauter

Abstract

We consider the wave equation in a boundary integral formulation. The discretization in time is done by using convolution quadrature techniques and a Galerkin boundary element method for the spatial discretization. In a previous paper, we have introduced a sparse approximation of the system matrix by cutoff, in order to reduce the storage costs. In this paper, we extend this approach by introducing a panel clustering method to further reduce these costs.
