[en] A sub-problem finite element method is developed for refining the inductor models in magnetic circuits. It applies electrokinetic, magnetostatic and magnetodynamic models on progressively more complicated geometries and different components of the solution, supported by different meshes. It allows an efficient and robust analyze of magnetic circuits in any frequency range, with an accurate calculation of Joule losses and forces in inductors.
