对线性RLW方程提出了一种结点沿特征方向移动的有限元方法并分析了该方法的收敛性,得到了最佳L^2及H^1模误差估计.
The finite element method with nodes moving along the characteristic direction is presented for linear RLW equation. The convergence properties of the method has been examined. The optimal order error estimates in L^2 and H^1 norms are obtained.
