A multiconductor model for finite-element eddy-current simulation

The stranded-conductor finite-element model does not account for the skin and proximity effects in a multiconductor system. The solid conductor model considers the true geometry, all the individual conductors, and their connections but may lead to unmanageably huge models. The multiconductor model proposed here, does not necessarily consider all geometrical details but instead, discretizes the inner geometry and voltage drop and enforces the typical current redistribution in multiconductor configurations in a weak sense. The magnetic and electric meshes are independently and adaptively refined which results in an optimal error control and accurate results for relatively small models.
