$H(\mathrm{curl})$和$H(\mathrm{div})$的部分间断节点有限元

Partially discontinuous nodal finite elements for $H(\mathrm{curl})$ and $H(\mathrm{div})$

Jun Hu, Kaibo Hu, Qian Zhang

摘要:

本文研究了$H(\mathrm{curl})$和$H(\mathrm{div})$在二维和三维空间中的部分不连续节点有限元离散化问题,在某些方向上具有不连续性的向量值拉格朗日有限元。这些空间可以实现为连续和不连续Lagrange元的组合,并适合于de~Rham复形。我们构造了条件良好的节点基。

英文摘要:

We investigate discretization of $H(\mathrm{curl})$ and $H(\mathrm{div})$ in two and three space dimensions by partially discontinuous nodal finite elements, i.e., vector-valued Lagrange finite elements with discontinuity in certain directions. These spaces can be implemented as a combination of continuous and discontinuous Lagrange elements and fit in de~Rham complexes. We construct well-conditioned nodal bases.
