Analysis of Uniform Magnetic Field Problem by Edge Elements - Effects of Reduced Integration and High Order Elements -

摘要

Uniform magnetic field problem is widely appeared in the validation at developing finite element software, and so on. However, it is difficult to realize the uniform magnetic field in distorted hexahedral isoparametric elements. Then, authors introduced the subparametric elements. Furthermore, the reduced integration of Gauss-Legendre quadrature is applied to the, first-order isoparametric hexahedral edge elements to improve the uniformity. In this paper, we discussed the effectiveness of various techniques to realize the uniform magnetic field.
