Hi!

I was trying to simulate an open container emptying under gravity. I want to find out the time taken to empty completely. It is a quasi steady state model if the liquid in it is incompressible and inviscid. I wanna know if I can do it as a PISO unsteady case as I m using VOF model or do I just go about using Implicit Unsteady case.

Don't think you can use PISO with VOF, also dont really understand what you mean by quasi steady state when your trying to simulate the emptying of a container, but just go ahead with implicit unsteady and make a nice movie
