Abstract
Eddy-current problems occur in a wide range of industrial and metallurgical applications where conducting material is processed inductively. Motivated by realising coupled multi-physics simulations, we present a new method for the solution of such problems in the finite volume framework of foam-extend, an extended version of the very popular OpenFOAM software. The numerical procedure involves a semi-coupled multi-mesh approach to solve Maxwell’s equations for non-magnetic materials by means of the Coulomb gauged magnetic vector potential A and the electric scalar potential φ. The concept is further extended on the basis of the mpressed and reduced magnetic vector potential and its usage in accordance with Biot-Savart’s law to achieve a very efficient overall modeling even for complex three-dimensional geometries. Moreover, we present a special discretisation scheme to account for possible discontinuities in the electrical conductivity. To complement our numerical method, an extensive validation is completing the paper, which provides insight into the behaviour and the potential of our approach.
