Abstract

The BEASY code is based on the Boundary Element Method (BEM) of Analysis which offers important advantages over the classical finite element approach. In BEM only the boundary needs to be discretized thus reducing by one dimension the data required to run a problem. Direct boundary element solution of the type used in BEASY gives displacements and stresses (or temperature and fluxes, etc.) with the same degree of accuracy, which makes the technique well suited to problems — for example involving stress concentration — where reliable and highly accurate results are required. Boundary elements are also well adapted to problems with infinite domains.

BEASY can solve potential — including temperature — and elasticity problems. The code has its own pre and post processing facilities and in addition interfaces with well known modelling systems such as PATRAN.
