January 27, 2014, 09:03	Choosing outflow BC	#1
zombiaska Member Simas Join Date: Mar 2012 Posts: 37 Rep Power: 14	Hello, I wanted to know which boundary condition I should use for my model. Earlier I used velocity inlet as 1,125 m/s and outflow is 1,59 m/s. I want to make my outflow velocity same as inlet 1,125 m/s. What Boundary condition I should use? From descriptions best fit is outlet-vent, but there is pressure gauge, not velocity. How I could calculate that pressure?
