Three-dimensional magnetostatic analysis using Nedelec's elements

Abstract

The authors demonstrate the effectiveness of a method which uses Nedelec's tetrahedral elements for finite-element approximations of the mixed formulations of three-dimensional magnetostatic problems. The fundamental unknown function can be the magnetic field intensity (H-method) as well as the vector potential (A-method). A verification problem established by the Institute of Electrical Engineers of Japan is solved with these methods. Also, a practical test with the H-method is shown. It is shown that the H-method produces fairly good results within a reasonable computation time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
