In two dimensions, we propose and analyze an a posteriori error estimator for finite element approximations of the stationary Navier--Stokes equations with singular sources on Lipschitz, but not necessarily convex, polygonal domains. Under a smallness assumption on the continuous and discrete solutions, we prove that the devised error estimator is reliable and locally efficient. We illustrate the theory with numerical examples.

带有Dirac测度的平稳Navier-Stokes方程的后验误差估计

SIAM科学计算杂志,第42卷,第3期,第A1860-A1884页,2020
年1月。在二维中,我们提出并分析了Lipschitz上具有奇异源的固定Navier-Stokes方程的有限元逼近的后验误差估计。 ,但不一定是凸多边形区域。在连续和离散解的小假设下,我们证明了设计的误差估计器是可靠的并且局部有效的。我们通过数值示例来说明该理论。
