| Popis: | This paper compares finite element formulations for modelling eddy current problems with jumps in conductivity. We study schemes which represent the eddy current regions using nodal or edge based magnetic vector potentials. The use of an additional electric scalar potential, V, in the eddy current regions is discussed. The nodal A scheme is shown to produce misleading results at low frequencies whilst the AV and edge A schemes are acceptable. |
