fixed waterlevel boundary

aquamen · May 29, 2015, 04:54

Hi guys,

I´m try to simulate a 3D modell, where I have a house with a cellar. Around the house I have a waterlevel which should be fixed (setFields, thats I know).

My problem now is, that with the begin of the simulation the water should flood the house (no problem till this point). But now the waterlevel should stay constant, even if the water fill the house ( no inflow boundary, because the value change during the simulation .

So my question is, how do I have to set the boundarys for this simulation?
Whats the right commands?

Thanks for help.

Hi
Which solver are you using? Maybe interFoam?
Matej Muller describes one possible way you could try.

However I wasn't able to get a stable simulation.

Maybe you have better luck and can share your experience

Good luck!
