Surface impedance-BEM technique for nonlinear TM-eddy current problems

Abstract
The impedance boundary condition (IBC) approximation is used to formulate the problem as an exterior one, in other words, in terms of only the exterior fundamental solution. The first order boundary element technique has been used to represent the boundary integral equation numerically. The Gauss–Seidel iterative procedure was applied. The results obtained with the present approach are in good agreement with those obtained experimentally and theoretically by other authors.
