采用非协调EQr1ot元对一类非线性抛物型方程进行了变网格有限元分析,利用该单元的相容误差比插值误差高一阶的特殊性质,得到了最优L2-模和最优能量模的误差估计.
In this finite element analysis is is one order higher than rived. paper, the nonconforming EQT' element is used to approximate nonlinear parabolic equations and the presented with moving grids. By using of the special property of the element, i.e. ,its consistency error the interpolation error. The optimal order error estimates under LZ-norm and broken H1-norm are de- rived.
