This chapter provides an introduction to the iso-geometric Boundary Element Method (BEM). The standard iso-geometric BEM is presented first and then isometric concepts are introduced. Both plane and 3-D problems are discussed and details of implementation given. The method is extended to non-homogeneous and non-linear problems.

On a hybrid boundary element method
Numerische Mathematik, 2000The author provides a fairly rigorous and elegant numerical analysis of a hybrid boundary element method which is already in use in some applications. He combines the advantages of the direct and indirect boundary integral formulations, furnishes a stability condition and the subsequent error estimate.

The field of boundary element methods (BEM) relies on recasting boundary value problems for (mostly linear) partial differential equations as (usually singular) integral equations on boundaries of domains or interfaces.

An operator is a process which applied to a function or a set of functions produces another function, i.e., $$[{\rm{L(u) = b}}$$ (1) where L(u) is the operator which applied to u produces b; u and b may be scalars or vectors; L( ) may be an ordinary differential operator such as $$[{\rm{L( ) = }}{{\rm{a}}_0}\frac{{{{\rm{d}}^{\rm{2}}}()}}{{

Abstract The boundary-element method is a powerful technique for solving partial differential equations encountered in various branches of computational physics and engineering. Examples include Laplace’s equation, Helmholtz’s equation, the convection–diffiusion equation, the equations of potential and viscous flow, the equations of ...

This chapter gives an outline of acoustic analysis using the boundary element method (BEM). In the first section, the fundamentals of the BEM and its application to sound field analysis are explained. The second section presents two advanced techniques, the indirect approach with degenerate boundary and the domain decomposition method.
