Gas-liquid vertical separator, problems with convergence
 
1 Attachment(s)
Dear friends, I have worked very hard on my thesis, but I have had problem with the convergence.
The boundaries conditions are:
Inlet: bulk Velocities (volume fraction of each phase)
Gas outlet (upper): pressure 0 psi
Liquid outlet (down): 0.35 psi (hydrostatic)

The model I am using is inhomogenues, specifically the particle model.
I am using the gravity vector due to the fact that I am modelling the gravitational effect (densities difference)
K-E for turbulence...
My simulation starts running but after 25 iteration this message appears :A wall has been placed at portion(s) of an OUTLET |
| boundary condition (at 100.0% of the faces, 100.0% of the area) |
| to prevent fluid from flowing into the domain.

I know what it means, the problem is that I have done several things but the problems continues.
Who can HELP ME ...
Thanks before hand
