In exactly the same way ... just continue your geometry over the tank edge, down the tank exterior wall and onto the surrounding floor...

I want to simulate such a tank filling: the inlet of the vessel is at the bottom,without outlet,and filled with air at 5000Pa. the liquid flow into it by the pressure of 0.5MPa. How should I set the domain and boundary conditions? Homogeneous Multiphase? Good luck to you! Regurds,James

By the way,How can I get the Animation of water flow? can you give me some advice in detail ?I know how to use the animate,but cannot solve this situation. Regards, James
