有限元法（FEM）是计算电磁学（CEM）领域中一种功能强大且常用的工具。它用于在具有任意材料属性的任意几何形状上以高保真度建模麦克斯韦方程;然而，它可能很难有效地获得解决方案。因此，通常从模型的离散化过程开始，然后通过网格细化慢慢引入更多的自由度（DoF）。本文讨论了一个有限元代码，支持各向异性的h-和p-细化，同时避免了一些常见的困难，实现了一个连续的Galerking有限元代码，支持h-细化的四边形或六面体元素。
The Finite Element Method (FEM) is a powerful and commonly used tool within the domain of Computational Electromagnetics (CEM). It is used to model Maxwells Equation’s with high fidelity over arbitrary geometries with arbitrary material properties; however, it can be difficult to arrive at solutions efficiently. Thus, it is common to start with a course discretization of a model, and slowly introduce more Degrees of Freedom (DoFs) through mesh refinements. This paper discusses an implementation of an FEM code which supports anisotropic h- and p-refinements while avoiding some common difficulties associated with implementing a continuous Galerking FEM code which supports h-refinement over quadrilateral or hexahedral elements.
