在本文中,提出了利用化粪池样条的配置方法对 Korteweg-de Vries-Burger 方程 (KdVB) 进行数值求解。应用冯诺依曼稳定性分析技术,我们表明该方法是无条件稳定的。通过对所获得的数值结果的绝对误差与方程的解析解进行比较,我们将测试所提出方法的准确性。
In this paper, a numerical solution for the Korteweg-de Vries–Burger’s equation (KdVB) by using the collocation method using the septic splines is proposed. Applying the Von-Neumann stability analysis technique we show that the method is unconditionally stable. By conducting a comparison between the absolute error for the obtained numerical results and the analytic solution of the equation we will test the accuracy of the proposed method.
