Default Tank simulation: Boundaries
  #1

Hello,

I am simulating a tank partially full of water. I have used different boundary contitions for the surface (pressure outlet, symmetry), inlet (velocity inlet) and outlet (pressure outlet and outflow). However, I've got a different solution for each combination. Could you tell me which are the best boundary conditions for simulating a free-surface water condition with an inlet and outlet?

I will appreciate your help,

Thank you

"I have used different boundary contitions for the surface (pressure outlet, symmetry)"

You don't need to define boundary conditions at the free surface. Just patch the regions with water or air and start the calculations.
