Kaibo Hu, Qian Zhang, Zhimin Zhang

摘要:

我们构造了二维光滑有限元de Rham复形。这导致了三个卷曲-卷曲协调有限元族,其中两个包含两个现有族。最简单的三角形和矩形有限元分别只有6和8个自由度。数值实验表明,每一个家庭的收敛性和效率的元素解决quad-curl问题。

英文摘要:

We construct smooth finite element de Rham complexes in two space dimensions. This leads to three families of curl-curl conforming finite elements, two of which contain two existing families. The simplest triangular and rectangular finite elements have only 6 and 8 degrees of freedom, respectively. Numerical experiments for each family demonstrate the convergence and efficiency of the elements for solving the quad-curl problem.
