Three-dimensional magnetostatic analysis using EDGE Element

변 요소를 이용한 3 차원 정자장 해석

If one express the basio equations of electromagne tics in terms of differential form, one can have many physical meanings. To obtain this advantages in Finite Element Method, we should use new element. In this study, we select degree of freedom as circulation A along edges of the mesh, and use Egde Element because A is i-form. We apply this method to some examples of the 3-D magnetostatics, and obtain decrease of total nonzeros and increase of accuracy.
