摘要：
This paper proposes a two-level defect-correction stabilized finite element method for the steady Navier-Stokes equations based on local Gauss integration. The method combines the two-level strategy with the defect-correction method under the assumption of the uniqueness condition. Both the simplified and the Newton scheme are proposed and analyzed. Moreover, the numerical illustrations agree completely with the theoretical expectations. (C) 2012 Elsevier Ltd. All rights reserved.
