Voltage and Current Sources for Massive Conductors Suitable With the A-χ Geometric Eddy-Current Formulation

The aim of the paper is to present an automatic and general technique, suitable with theA-χgeometric eddy-current formulation, to impose sources over massive conductors of any shape. For this purpose, thelocalized source approachis used, which does not require the solutions of steady-state conduction problems in the preprocessing stage. Nevertheless, this approach needs athick cutin each active conductor, which is usually found “by hand.” In this paper, an automatic and general algorithm to compute such thick cuts is introduced. Some benchmark problems are presented to demonstrate the generality and the robustness of the algorithm.
