Abstract

A software package for solving time-harmonic 3-D eddy current problems using the boundary-element method (BEM) is described. The package solves coupled boundary integral equations for the magnetic vector potential and the electric scalar potential within the conductors, and for the magnetic vector potential in non-eddy-current regions. The authors describe the boundary integral formulation and its BEM realization. As an example, the eddy current field of a nonmagnetic conducting cube immersed in a homogeneous magnetic field with harmonic time variation is calculated. Additional numerical results are presented for a multiply connected eddy-current problem (benchmark problem No. 7 defined by the International TEAM workshops). The boundary-element solutions are compared with finite-element results and show excellent agreement
