I'm working in a 3D sewer pipe model.
I've worked the inlet condition in several ways trying to get an appropiate result of the free flow.
First I tried cutting the inlet face to the half, and setting the bottom half as the water inlet condition and the upper half as air.
This is the result I get:


I also tried setting the whole inlet face as water, but the result is not what I'm looking for neither:


What I'm looking to get as a result should be a water profile near to this (as it's free flow in pipes):

I've read about how to represent free surface in ANSYS and about the Open Channel Flow the software has...
But I'm not really sure if I should set the water level by cutting the inlet face to the level I wish or if I should definitely work with the Open Channel Flow, or if there is a better way to represent what I'm modelling...

Please if any one could give me some advice or guidance it would be very helpful.
