A Numerical Investigation for a Model of the Solid-Gas Phase in a Crystal Growth Apparatus Jurgen Geiser 1* 1 Humboldt-Universitat zu Berlin, Department of Mathematics Unter den Linden 6, D-10099 Berlin, Germany.Received 22 December 2006; Accepted (in revised version) 6 September 2007 Available online 11 December 2007 Abstract We present discretization and solver methods for a model of the solid-gas phase in a crystal growth apparatus. The model equations are coupled Eulerian and heat-transfer equations with flux boundary conditions. For a more detailed discussion we consider simpler equations and present time- and space-decomposition methods as solver methods to decouple the multi-physics processes. We present the error analysis for the discretization and solver methods. Numerical experiments are performed for the Eulerian and heat-transfer equation using decomposition methods. We present a real-life application of a crystal growth apparatus, based on underlying stationary heat conduction. Finally we discuss further error analysis and application to a more complex model of crystal growth.
