COMPUTER DIAGNOSIS SYSTEM FOR THERMAL ANALYSIS BY BEM AIDED WITH SIMPLE CAD.

The authors present a computer tomographic system COMTOS-BEM based on three-dimensional boundary element analysis: it houses its own geometric modeling and automatic mesh generation. Furthermore, it supports design feedback reactions to change modeling or meshing, make recalculations, and renew boundary conditions. In this paper, the basic concept of the proposed computer diagnosis system and the necessary geometric modeling and processing and boundary element formulations are presented. Some numerical examples illustrate the validity and effectiveness of the system in practice.
