1 引言有限体积元方法(FVEMs)作为处理偏微分方程的有效数值方法,得到了广泛的应用.已有文献多为处理单个方程,对于方程组的情形此类文献甚少.羊丹平对于一维抛物型方程组构造了一次广义差分格式.Douglas就一类抛物型方程组讨论了一般的
High order finite volume element method for a class of nonlinear parabolic systems is presented and analyzed. Optimal L2 convergence rate for finite volume element method is proved.A numerical experiment shows the method reduce work time greatly without losing accuracy.
