Abstract

Three-dimensional eddy current equations are formulated in terms of a magnetic vector potential A and an electric scalar potential V in the conductive regions and a reduced magnetic scalar potential Ω in the nonconductive region. A finite-element computer code, EDDY3DT, has been developed using this A-V formulation. Application to test problems and comparison with the analytical solutions or results by other methods show that the A-V formulation is effective for problems involving anisotropic and discontinuous conductivities, cracks, and holes
