Adaptive boundary element method for acoustic scattering problems

Andrzej Karafiat
The subject of the paper is an application of the boundary element method to problems of scattering of acoustic waves by an elastic solid submerged in a fluid. A model problem of linear acoustics with a simplified fluid-solid interaction on the boundary is considered. The problem is described by the Burton-Miller integral equation. The Galerkin method is used to obtain an approximate solution. Adaptive methods of approximation are discussed. Some a posteriori error estimates are given.
