2D Airfoil - Dimensions & boundary conditions -CFX
 
Hello. If Im not wrong, its not possible to make a directly 2D analysis in Ansys CFX. Does anybody knows:

1. Which is the tickness value of the airfoil? so I can simulate a 2D analysis. 2. What boundary conditions should I apply to the walls, that define the thickness ( not the inlet-outlet, and Up-Down walls) 3. What kind of mesh do you recommend me? O-Grid?

Thanks in advanced. Santiago

1) Single cell thickness 2) Symmetry 3) Yes

1.Single cell thickness? I got lost, sorry. Can you please specify? Thanks a lot! Santiago.

You extrude your 2d shapes/faces into the 3rd dimension, just 1 cell deep.

(sounds like something out of the matrix!)
