SPECIAL FINITE ELEMENTS FOR EFFICIENT COMPUTATION OF MAGNETIC HELD IN r‐z AND r‐φ GEOMETRY

Abstract

This paper presents ‘infinite’ finite elements for magnetic field problems with open boundaries in r‐z and r‐φ geometries. The formulations of the elements are so simple that closed‐form expressions for the element matrix are obtained. In order to test the new elements, simple examples, for which analytical solutions exist, are analysed.
