[interFoam] pipe flow - phase piling up at outletpatch ?!

MangoMango · October 6, 2014, 16:41

Hi,

I need to simulate a turbulent twoPhase pipe flow.
The is set up with interFoam.

It works fine until the liquid phase hits the outlet-patch - then the pipe will fill up. No "drop" of the liquid Phase passes the boundarypatch. I know that it has to be a problem with the bc ...I tried several bc inletOutlet, pressureInlet ...but I cant figure out a way that will bring both phase through the patch.

It would be great if anyone could give a glance at this....Im somehow puzzeld.

best regards
Alex
