摘要

对于非定常二维对流扩散方程，将二次迎风插值方法（ＱｕａｄｒａｔｉｃＵｐｏｔｒｅａｍＩｎｔｅｒｐｏｌｓｔｉｏｎｆｆｏｒＣｏｎｕａｃｔｉｖｅＫｉｎｅｍａｔｉｃｓ，简称Ｑｕｉｃｋ格式）与集中质量九节点等参元的有限单元法结合起来，发展了一种有效的高精度差分有限元破开算子法．计算结果表明，这是一种高精度的数值模式．

Abstract

in this paper

a ADM-FEM operating spliting method with higher order-accuracy for 2D unsteady convection-diffusion equation is developed hosed on [1]

which combines OUICK scheme with FEM with nine point isparameter elements.
