A general purpose 3D formulation for eddy currents using the Lorentz gauge

Abstract

The Lorentz gauge formulation is shown to be easily extendable to handle transient and multiply connected problems in a robust manner. It is demonstrated that the extensions to handle multiply connected problems also provide a mechanism for tackling configurations that are not immediately amenable to the standard deployment of A and phi throughout the solution domain; i.e. A is used in conductors and phi in nonconductors. This work on the classical Lorentz formulation has resulted in a commercial code, ELEKTRA.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
