Default VOF model-Channel flow-Boundary condition
Posts: n/a

I am trying to model a simple channel flow with the Vof model, so i have water + air at the inlet... I have seen some topics dealing with the setup but cant get it to work properly.

the inlet condition should be fine; i have 1 for water and 1 for air.

what i dont know how to set up is the pressure outlet, should open channel flow be checked? since i know the height of water at the outlet, shouldnt the pressure at the outlet be specified? (po*g*h)

I have symmetries on the side, wall at the bottom, and tried pressure outlet/wall at the top.

This is something i have done with no problem in cfx, just seems more difficult to get here. And a good tutorial is missing in the help.

Any help would be great.
