Overflow boundary condition?

  1. Apr 21, 2010 #1
    Apparently Fluent has this thing called an "overflow" boundary condition. I tried searching the help files and found absolutely nothing about it. Does anyone know what this is and why someone would want to use it?

    Hmmm, google turned up nothing except a few vague references to using an OVERFLOW boundary conditions (note that all references I found used an all-caps notation). Even a journal search turned up nothing.

    Perhaps it has to do with actual overflow. That is, it can be a "liquid-only" outflow boundary condition at a free surface?

    Other than that guess, I haven't a clue; I've never heard of it.
