Hi, I am beginner in Fluent. my model involved interface. When I did my model in steady state, the velocity distribution seem nice as attached. However, when I did it in unsteady state, there was sudden jump at the interface. I totally do not have any idea to solve it. Pls help me. It is urgent. Any solution in solving my problem? Thanks for help.
