摘要

摘要在本文中，我们提出比较Poisson问题和Stokes问题的三种后验误差估计量，即平衡的、基于星的和基于残差的后验误差估计器，它们具有最低阶Crouzeix-Raviart有限元离散化。给出了数值结果，以比较自适应细化策略中三种估计器的性能。

Numerical comparison of three a posteriori error estimators for nonconforming finite element method

Abstract In this paper, we propose to compare three a posteriori error estimators namely equilibrated, star-based and residual based for the Poisson problem and the Stokes problem with lowest-order Crouzeix-Raviart finite element discretization. The numerical results are presented to compare the performance of the three estimators in an adaptive refinement strategy.
