Default frustration in VOF

Hi All, I find the VOF modeling of Fluent is very frustrating. Until now, I don't have any confidence of this multiphase model. Could you pls share your experience on: how to get solution from an unsteady (initially unsteady in nature) stat to a steady free surface state using VOF in Fluent??

So far my experience is that it takes too long to obtain steady state and that the initial conditions rules the convergence of the problem. Another experience I can share is that is quite frustrating. Anyway fluent is not the best for this kind of problems.

Cheers

CFD newbie

I don't have hands on experiences but I've heard about flow3d and CFX-4. Can someone give an opinion?

Regards

Hi Newbie Do you know any bugs in fluent6 (VOF)? Did you have any prob like disappearance of one fluid even though the solution converges?

Not so far, my only complain is the time of convergence. It takes ages to arrive to steady state.
