Magneto-thermal behavior finite element analysis for ferromagnetic materials in induction heating devices

The authors present a finite element formulation, based on a direct solution of a system of dynamic, nonlinear and coupled magnetothermal equations, for ferromagnetic materials in induction heating devices. This formulation insures a real coupling between the equations. Thus, the results are more precise than those obtained from the classical modeling, and the magnetothermal problem simulations are faster and easier to perform.>
