有限元转换的通用方法

A general approach to transforming finite elements

Baylor University(贝勒大学)

Robert C. Kirby

AI总结:

本文提出一种通用方法,通过研究有限元节点之间的关系,解决Hermite、Morley、Argyris和Bell等有限元在标准方式下无法与参考元素结合的问题。

摘要:

在有限元代码中使用参考元素,该元素上的有限元基函数被构造一次并映射到网格中的每个单元,大大提高了结构和效率。然而,许多著名的有限元如Hermite、Morley、Argyris和Bell并不具备与参考元素标准结合所需的等价性。本文通过研究有限元节点在推动下的关系,提出了一种通用的方法来映射这些有限元的基函数。

英文摘要:

The use of a reference element on which a finite element basis is constructed once and mapped to each cell in a mesh greatly expedites the structure and efficiency of finite element codes. However, many famous finite elements such as Hermite, Morley, Argyris, and Bell, do not possess the kind of equivalence needed to work with a reference element in the standard way. This paper gives a generalizated approach to mapping bases for such finite elements by means of studying relationships between the finite element nodes under push-forward.
