Hi, everybody I try to simulate unsteady flow in a corrugated channel. I want to use periodic boundary condition for reduced computatioal domain, but in the fluent mannual said that

"Note that transient simulations for fully-developed fluid flow are not valid with translational periodic flow"

Can I use periodic condition with unsteady simulation?

Plase tell me :-}

Thanks

Somchai

I think the manual means something else. You can use periodic conditions for unsteady flows.
