Solution of Eddy Current Non Linear Problems

Fabio Freschi, Politecnico di Torino The work presents a two stage approach to solve a class of nonlinear 3D eddy current problems with high saturation, typical of induction heating processes. The proposed method separates the problem of heavy nonlinearity from the complexity of the geometry, by resorting to a 1D fast nonlinear solver which is coupled with a CST 3D solver. Under certain hypotheses on the geometry, the approach is shown to be effective and accurate. Comparison with the full 3d nonlinear approach obtained with a commercial code will be provided.
