THERM3D: A boundary element computer program for transient heat conduction problems
Abstract
The computer code THERM3D implements the direct boundary element method (BEM) to solve transient heat conduction problems in arbitrary three dimensional domains. This particular implementation of the BEM avoids performing time consuming domain integrations by approximating a 'generalized forcing function' in the interior of the domain with the use of radial basis functions. An approximate particular solution is then constructed, and the original problem is transformed into a sequence of Laplace problems. The code is capable of handling a large variety of boundary conditions including isothermal, specified flux, convection, radiation, and combined convection and radiation conditions. The computer code is benchmarked by comparisons with analytic and finite element results.
