摘要
对空间和时间坐标分别采用三次B样条有限法和Crank-Nicolson差分法求得非线性BBMB方程的数值解,应用Von-Neumann稳定性理论证明了此方法的无条件稳定性,并且通过两个例子验证了该方法的有效性与可行性.
A cubic B-spline finite element method for the spatial variable combined with a Crank-Nieolson scheme for the time variable is proposed to approximate a solution of Benjamin-Bona-Mahony-Burgers (BBMB) equation. Von-Neumann scheme is proposed to analyze the unconditionary stability of the present method. Finally, through two examples we demanstrate the effectiveness and feasibility of this method.
