Abstract

Application of the adaptive multi-level method to industrial heat conduction problems G. Lobel Corporate Research and Development, Siemens AG, ZFE BT SE33, 91050 Erlangen, Germany ABSTRACT The adaptive multilevel method is an innovative approach of finite element me- thods to the solution of partial differential equations. A new code, developed at 'Konrad-Zuse-Zentrum fur Informationstechnik' in Berlin as implementation of this method for two-dimensional parabolic problems has been tested on several realistic problems of heat transfer in electronics industry. The new method offers a lot of capabilities for numerical simulation, that could not easily be provided by conventional methods. Especially in applications with singularities, multiple scales, complex distributions of materials and moving heat sources the new method has promising advantages. Furthermore its simple usage opens the powerful possibilities of the finite element method to the non-expert. INTRODUCTION The finit
