T. Onuki et al., HYBRID TREFFTZ AND FINITE-ELEMENT METHOD APPLIED TO MAGNETIC-FIELD ANALYSIS FOR ROTATING MACHINES, IEEE transactions on magnetics, 33(2), 1997, pp. 2014-2017
This paper describes a hybrid approach of the finite element method an
d the boundary type solutions, i.e. the Trefftz method and the boundar
y element method, for analyzing the magnetic field in rotating machine
s. This approach has the advantage of obtaining continuous physical qu
antities precisely without the singularities in calculating boundary i
ntegrals. Its application to a concrete model is also presented.
