A Nyström solution of the quasi-magnetostatic volume integral equation for eddy current analysis

A time-harmonic quasi-magnetostatic volume integral equation is formulated for the eddy currents and magnetization in a conducting, magnetic material. The integral equation is solved using the Locally Corrected Nystrom (LCN) method. The formulation is capable of handling mixed meshes of hexahedral, prism, and tetrahedral elements. Several problems are analyzed and error convergence plots are presented.
