摘要：
In this paper, a two-level defect-correction Oseen iterative finite element method is presented for the stationary conduction-convection equations based on local Gauss integration. The method combines the defect-correction method, the two-level strategy, and the locally stabilized method. The stability and convergence of the proposed method are deduced. Finally, numerical examples verify the theoretical results of the proposed algorithm and show that it is highly efficient and reliable for the considered problem. (C) 2014 Elsevier Ltd.
