How to simulate a vessle with air water phases?
 

Dear all.

I am trying to simulate a vessel with containing air and water phase in OPEN FOAM. The geometry is quite complex so I don't want to use snappyHEXmesh.
I made my geo and mesh in ANSYS and then I imported to openfoam.
I already created single phase but now I want to make it two phase.


I would be glad if SB could help me out.
