论文摘要
我们提出了一种混合有限元方法，用于stokes流动，每个元素的自由度和简单网格方面的自由度。该方法是通过考虑涡度 - 速度压力公式的，并通过使用正交规则在局部消除涡度。离散溶液无分量无差，该方法是压力鲁棒的。理论得出的收敛速率通过数值实验证实。
We propose a mixed finite element method for Stokes flow with one degree of freedom per element and facet of simplicial grids. The method is derived by considering the vorticity-velocity-pressure formulation and eliminating the vorticity locally through the use of a quadrature rule. The discrete solution is pointwise divergence-free and the method is pressure robust. The theoretically derived convergence rates are confirmed by numerical experiments.
