Abstract

AbstractThis paper investigates a computationally efficient strategy for simulating induction heating processes, using a multiharmonic ansatz and harmonic balancing for the solution of the nonlinear magnetic eddy current problem in frequency domain. In order to increase the flexibility of the meshing procedure and decrease the number of degrees of freedom, a methodology for nonconforming interfaces and Nédéléc edge elements is presented. The verification of the proposed method is carried out by comparison to the conform (conforming mesh) solution. Furthermore, the results from the eddy current problem are used to simulate the temperature distrubution in a thin steel sheet and compute the resulting stresses.
