H-METHOD FOR SOLVING 3D EDDY-CURRENT PROBLEMS

A novel finite element model, which uses magnetic field intensity H as a state variable in the whole solution region of 3D eddy current prob lems, is presented. A surface integral on the interface, which leads t o asymmetric equations in discretization, is considered in this formul ation. The formulation uses consistently linear edge elements and flux continuity is ensured by imposing del . B=0 with the penalty method, Numerical results of the problem No. 3 of the TEAM WORKSHOP are provid ed, showing the validity of the algorithm.
