Abstract

The fast multipole method (FMM) is designed to speed up the matrix-vector multiplications in an iterative method. We apply the FMM and the ray propagation fast multipole technique to the boundary element method (BEM) for elastic wave modeling. We discuss how the new techniques are used to solve two-dimensional solid-solid (penetrable) surface scattering problems where the solids are assumed to be bonded at the interfaces.
