Abstract

The Boundary Element Method is developed in its most simple form; for the solution of Laplace’s equation in an interior domain with a straight line approximation to the boundary. The direct and indirect approaches to the boundary element method are included. The methods are developed in Freemat, a language similar to Matlab. The codes for the solution of Laplace’s equation in a general domain with a general (Robin) boundary condition are developed. The codes are applied to a typical test problem. The codes are made available as open source (BEMLAP-MAT package) and can be downloaded from this paper or from the websites listed below2. The overall package is expected to become a teaching aid in the MSc course3 that is presently being developed by the authors.
