摘要:

我们考虑三维空间中光滑闭超曲面上的曲面Stokes方程。对于该问题的离散化,文献中使用了Dziuk-Elliott的曲面有限元方法(SFEM)的推广与Hood-Taylor有限元空间对的组合。我们将此方法称为Hood-Taylor-SFEM。该方法使用罚函数技术来弱满足切向约束。在本文中,我们给出了该方法的离散化误差分析,得出了能量范数下的最优离散化误差界。我们还讨论了与系统矩阵(预)条件化相关的线性代数问题。

英文摘要:

We consider the surface Stokes equation on a smooth closed hypersurface in three-dimensional space. For discretization of this problem a generalization of the surface finite element method (SFEM) of Dziuk-Elliott combined with a Hood-Taylor pair of finite element spaces has been used in the literature. We call this method Hood-Taylor-SFEM. This method uses a penalty technique to weakly satisfy the tangentiality constraint. In this paper we present a discretization error analysis of this method resulting in optimal discretization error bounds in an energy norm. We also address linear algebra aspects related to (pre)conditioning of the system matrix.
