Using Freestream - what is "Inlet Value"?

Question, what is the Inlet Value shown in the Freestream input for boundary condition? There are no units, so I thought it was phase fraction. Is that not correct?

I am trying to model an open ended vent pipe on a main pipeline that is gravity flow.

Thanks,

Hey @S_Bradley!

Is this a passive scalar transport simulation? Could you please share the simulation so that we can have a look at it?

Best,

Unfortunately, it is the same air/water two phase problem I have been working on for about two months now. I reduced the pipeline study area significantly to try and get it to converge, but no luck yet so I was exploring other methods to get to an answer. I now have to believe I am doing something wrong with the boundary conditions, so I was exploring that.
