摘要
运用修正局部Crank-Nicolson方法解流方程,得到了一种新的计算简单、无条件稳定的显式格式。计算结果表明,新格式的计算结果与精确解吻合较好,与原Crank-Nicolson格式相比计算误差明显改善。
The Modified Local Crank-Nicolson method being used to solve the convection equation,a new display mode with simple calculation,unconditional and stability has been obtained.The computed results have shown that the new mode is in excellent agreement.Compared with the original Crank-Nicolson method,the error of this method has a significant improvement.
