Abstract

In this paper, a numerical method used in computer graphics to solve global illumination problems is applied to heat radiation. The radiosity equation is solved by an adaptive finite-element method and linked to heat conduction. The method is validated on an analytic benchmark problem. Due to the speed up compared with commonly used methods for heat radiation, this approach might be a way to solve complex three-dimensional problems in high temperature environments.
