Boundary Conditions for Incompressible Flow
 
Hi everyone. These forums have helped me out a lot thus far, but I have a new problem that I can't seem to get around. I am modeling a 3D aircraft in FLUENT 6.2 with a flow speed of 30m/s. The aircraft geometry is symmetric, and therefore only the left half of the aircraft is being modeled. I pretty much followed the GAMBIT tutorial for creating a flow volume brick, etc. My problem right now is that I can't figure out what boundary conditions to use for the faces of the flow volume brick since the only far field options are pressure far-field...are these applicable for incompressible flows? If not, what boundary conditions should I use? The other boundary conditions I have specified are Symmetry for the symmetry plane, and Wall for the aircraft surface.

Also, I read that perhaps I should use the Segregated Solver for incompressible...would that be the best option for my case? Thank you very much for your help. -BL
