摘要：

In this paper we solve a free boundary problem for a system of partial differential equations modelling the thermoelectrical behaviour of an aluminium electrolytic cell. A fixed domain method is proposed which relies upon a weak formulation of this system. A discretisation is introduced by using pentahedral finite elements of six degrees of freedom. To solve the discretised system an iterative algorithm is proposed. Numerical results are given both for a test example and a real industrial situation.
