Three Dimensional Eddy Current Calculation Using Edge Elements for Magnetic Vector Potential

ABSTRACT A numerical method for the three dimensional eddy current in conductors by time varying applied fields is proposed using the finite element method. Edge elements are implemented for the magnetic vector potential A in A-V and A-V-ω methods. The uniqueness of the solution and the equivalence between A-V and A* (modified A) methods are proved by the formulation based on edge elements with the help of a graph logic. Results of some numerical tests show the efficiency of the method.
