BEM formulation with virtual eddy current density and magnetic field strength for 3-D eddy currents and its massively parallel implementation

Based on the BEM formulation with E/spl I.oarr/ and H/spl I.oarr/ derived by one of the authors, an improved formulation has been proposed in this paper by using virtual eddy current density J/spl I.oarr//sub v/ and magnetic field strength H/spl I.oarr/ for 3-D eddy currents. The equation system derived by the second formulation is better conditioned than that obtained from the first one. A massively parallel algorithm for the proposed BEM formulation is discussed and has been implemented on a massively parallel supercomputer (CM-200). One numerical example is given. The comparison between numerical and analytical results shows a good agreement.<
