COMSOL Multiphysics has been applied to develop a model for inductive heating. A coarse, lumped model of the interior of a high temperature reactor is coupled to finite element models for the electromagnetic field, the temperature distribution outside the reactor, and mechanical stresses in the crucible. The model can be applied to study operational conditions, thermal stresses, or design details for a high temperature reactor. Testing showed that special treatment of the numerical solution procedure is required for this type of highly non-linear model. It is suggested that the overall fundamental balances are used as additional parameters to check the quality of the non-linear solution.
