Abstract

The numerical analysis of problems involving eddy currents developed in thin skin effect depths, based on the classical finite element method, is extremely laborious and time consuming. Furthermore, the related geometries are not, usually, simple enough to permit an analytical solution. The present work is based on a new type of element enabling efficient modelling in such cases. It combines the increased accuracy and speed of analytical solutions for large subdomains, a reduced number of unknowns and the advantages of functional minimization procedures. An example concerning eddy currents calculation in a solid iron salient part is used to test the method´s performance
