I'm tryng to simulate a waterfall with rasInterFoam and I'd like to compare these results with another simulation made with Fluent.
As BC at the atmosphere in Fluent I have pressureoutlet, in which I can set Turbulent Intesity and Viscosity Ratio.
But if I set pressure outlet in Openfoam I have zerogradient for k and epsilon at the BC, and what I see is that k and epsilone go to zero in the domain while in Fluent they are constant.
Could someone give me some advice on which BC could I set to replicate the same case thate I have in Fluent.

I would also be interested in this question.
I have a pipe flow with a fix inlet velocity and pressure. At the outlet I want to have the resulting pressure, but with zeroGradient it doesn't seem to work so fine. Shouldn't it also be able with pressureOutlet - but therefor I need a entry for value, but which?
