Eddy Current Analysis Using a Nyström-Discretization of the Volume Integral Equation

A high-order Nystrom discretization of a volume integral equation derived for quasi-magnetostatic, time-harmonic eddy current analysis is presented. The formulation is based on the coupled magnetic field and magnetic vector potential integral equations. Both magnetic and conducting materials are included in the formulation. Analytic results for canonical problems are used to corroborate the high-order convergence of the method. Data for the TEAM Workshop problem 7 are presented.
