Hi

Turbulence modelling is available in vof, but its not suitable for multiphase problems. e.g I had simulated flow around a ship using VOF, k-epsilon model and I found that resistance was over predicted. It was more then twice the experimental value.

Laminar model agreed better with the experimental results.

Hi Satyanarayana

Try VOF (geometrical reconstruction), laminar, unsteady ( for both steady and unsteady state problems)..

What error are you getting? You might be getting it because of wrong inputs.

Regards, Manoj
