MAGNETIC FIELD COMPUTATIONS IN THE INTERIOR AND EXTERIOR REGIONS BY USING INFINITE ELEMENTS Available to Purchase

This paper describes numerical tests for a three dimensional infinite element suitable for finite element modelling of open boundary field problems. The infinite element has four nodes and is compatible with conventional cuboids. The effectiveness of the infinite element in the interior — finite element region is shown by comparing the accuracy and the CPU time when various boundary conditions are applied. The possibility of computing the external fields is also illustrated.
