engwlc Guest Posts: n/a	1. In the explicit scheme of finite element method, I have found the numerical result of one dimensional unsteady couette flow is unstable and divergent. What is the reason? 2. Also, the explicit scheme of finite volume method, the numerical result of one dimensional unsteady couette flow is oscillated. Why? ENGWLC
