I am attempting to do a multiphase study that consists of water and air. Instead of using a Geometry Primitive to initialize my water domain I would like to select a volume that is part of my imported model. You can see my setup here:
My issue is the use of 3 volumes, 2 that are Air and 1 that is Water. Where the Air volume meets the Water Volume I would have a free surface. The geometry at this free surface location is made up of 2 faces (one from the Air volume and one from the Water volume). Is there any boundary condition that I can add at this free surface interface that would allow the tank to level itself?
I understand that I could do this with geometry primitives. However, It would be nice to be able to model the Water volume and air volumes in CAD and take care of this interface with a Boundary Condition.
