Abstract
The nodal finite element realization of the T-Omega method involving a gaug ed current vector potential, T, is shown to yield erroneous results if appl ied to 3D eddy current problems with reentrant corners in the conducting re gion. The reason for the problem is pinpointed and a remedy is suggested.
