Electromagnetic Field Computations by the Hybrid Fe-Be Method Using Edge Elements

The authors present a hybrid finite-element (FE) and boundary-element (BE) method using edge elements for an open-boundary 3-D electromagnetic problem. In this method, the modified magnetic vector potential A* and the magnetic field intensity H are adopted as the physical quantities. The appropriate BE discretization described makes it easy to couple the BE region with the FE region through the transformation of unknown variables. Several practical applications of this method to 3-D eddy current problems are presented. The calculated values agree well with the experimental results. >
