Abstract

We propose a pair of approaches to account for voltage driven coils when solving 3D eddy-current problems with a discrete geometric approach. The formulation we use is based on the circulation a of the magnetic vector potential on primal edges and on a scalar potential χ on conductor primal nodes. The proposed approaches consider distributed or localized voltage sources respectively and they can be applied to general coil geometries. The results are compared with those obtained with Finite Elements.
