problem in VOF
 

I am going to simulate a two phase flow through VOF in fluent, now the problem is after simulation ending when I see the domain there is like the second phase didnt move at all, I tried for different B.C. but still there is no difference

Check at Run Calculation your Time Step Size or your Number of Time Steps. It should be different of 0.

thanks Toure, it was my post processing problem, seems to be okaid now, thanks again

same robleme, but not the solution, in the end of calculatiing, i find always one phse, knowing that before u used two phases (air + benzene)
thanks

did u patch the second phase?

Hamid did you use two inlets or single inlet? do u have a pipe flow?

mine are two pipes inside each other while the inner pipe will suck the fluid moving inside the outer pipe,let say one inlet and two outlet, kind of ..., just reminding u, after adapt region u v to patch in initialize menu the second phase, also in before u have to set the second phase like o at inlet ...

You mean that you have annuls?
