Abstract :
For pt.I see ibid., p.23-31 (1992). This paper presents a method for solving this model. The finite element formulation allowed for ease in modeling geometry, material properties, constraints, and boundary conditions. A direct substitution iteration scheme was employed with the finite element method to compensate for the material nonlinearity in the electromagnetics problem
