An Improved Time-Harmonic 2-D Eddy Current Finite-Element H Formulation

A finite-element formulation in terms of the magnetic field intensity is developed for 2-D eddy current problems, such that the current density lies in a plane, whereas the magnetic field is normal to such a plane. This type of configuration arises in the analysis of nondestructive testing of pipes, evaluation of transformer tank wall losses, and other applications. By conserving the displacement current, even for low-frequency cases, multiply connected domains and regions with very low conductivity are easily handled. Procedures for loss evaluation, mesh adaptation, and consideration of ferromagnetic materials have been developed.
