An axially symmetric multiphysics model for industrial induction furnaces has successfully been converted from COMSOL Multiphysics version 3.5a to version 4.2. The model combines computation of magnetic fields, heat transfer and thermal stresses. The inner part of the furnace is described by a few discrete state variables.

While the current in the induction coil is input in COMSOL, the model applies an equation for power control, temperature control or a combined power/temperature control. A few case studies have been selected to show differences between the control alternatives. Conductive or non-conductive liquid content can be handled. Quasi-stationary and dynamic simulations can be applied to study operational conditions, thermal stresses, or design details.
