电磁场计算中的棱边有限元法

Edge Elements with Applications to Calculation of Electromagnetic Fields

本文给棱边有限元下了一般性的定义，对棱边有限元法的性质进行了分析，导出了六面体的１－形式插值基函数和电磁场统一边值问题的棱边有限元方程，并用棱边有限元法计算了一个三维磁场问题。

The general definition of edge elements is given. The general properties of edge elements are discussed. Interpolation function of 1-forms for hexahedral elements is derived. Edge elements equation is obtained.An application of edge elements is given for the computation of 3D magnetic field.
