Hi,

I am new to CFD and am using STAR to analyze the flow around a wing, at about mach 0.2. In the best practices manual STAR-CCM+ provides, it mentions to use a velocity inlet and pressure outlet for my speed regime. How do these work and how do I know what pressure to specify at the outlet.

I appreciate any information/help on this.

If you're interested in how these specific boundary conditions are implemented mathematically, I recommend finding a copy of "Computational Fluid Dynamics" by Anderson and/or doing a bit of a search online (CFDOnline wiki too).

You shouldn't have to define a pressure for the pressure outlet and should just leave it as is.

Thanks man, I'll check out that book.
