Boundary Conditions in Gambit for a dam break model
 
Hi,
I created a mesh for a 3D dam break model. I plan on doing a VOF model with LES. I have two volumes; water and air. I am unsure of what to name the side where the vertical dam is ( the front of the water volume). Also the end of the flume is a free fall, what is the boundary condition for a free fall? I have decided to name the top of the water surface that meets the air volume as interface, should this be something different? Thank you for your time

Regarding VOF, just set 2 separated fluid domains in Gambit (icon next to BC)
You don't need to set any fluid interface

Ensure you patch the water domain before calculation...
