任意维$C^r$协调有限元空间的构造

A Construction of $C^r$ Conforming Finite Element Spaces in Any Dimension

Jun Hu, Ting Lin, Qingyu Wu

摘要:

本文提出了一种构造任意维数上具有任意$r$的$C^r$协调有限元空间的方法。证明了若$k \ge 2^{d}r+1$,则$\le k$次多项式空间$\mathcal P_k$可作为$d$维$C^r$有限元空间的形函数空间.这是第一个工作构造这样的$C^r$符合有限元在任何尺寸在一个统一的方式。它解决了有限元法中一个长期存在的问题。

英文摘要:

This paper proposes a construction of $C^r$ conforming finite element spaces with arbitrary $r$ in any dimension. It is shown that if $k \ge 2^{d}r+1$ the space $\mathcal P_k$ of polynomials of degree $\le k$ can be taken as the shape function space of $C^r$ finite element spaces in $d$ dimensions. This is the first work on constructing such $C^r$ conforming finite elements in any dimension in a unified way. It solves a long-standing open problem in finite element methods.
