Hey foamers!

I'm advancing on my case of study but now the "problem" is about what BC I've to put in the outer patch. The solver used is a modified MRFInterFoam to get some things but not so different from the original one.

The case simulates a rotating tank with fluid which drops due to the rotation. The "problem" is that I don't know which condition I should use to get the fluid out of the domain cause it must disappear.

Here you can see an image of my case:
t=0s:

t=2s:

The images show the evolution of alpha1 in time, start and ending of simulation.

Here's my doubt:
Is there any condition similar to OutletInlet in which I don't have to specify values cause I really don't know the speed, pressure or alpha1 that the flow is going to get. Any ideas?
