Abstract
This paper presents an overview of basic concepts, features and
difficulties of the boundary element method (BEM) and examples of its
application to exterior and interior problems. The basic concepts of the
BEM are explained firstly, and different methods for treating the
non-uniqueness problem are described. The application of the BEM to
half-space problems is feasible by considering a Green's Function that
satisfies the boundary condition on the infinite plane. As a special
interior problem, the sound field in an ultrasonic homogenizer is
computed. A combination of the BEM and the finite element method (FEM) for
treating the problem of acoustic-structure interaction is also described.
Finally, variants of the BEM are presented, which can be applied to
problems arising in flow acoustics.
