External flow BC
 

Hi everybody I am simulating a 2D wing profile near a wall. At the bottom side of the domain I have a wall, at the left I have an inlet. Does anybody know what is the best combination of the other boundaries? Wall at the top end outlet at the right or pressure both at the top and at the right? Are there any other combinations? Any help apreciated.

inlet at left outlet at right wall slip up ( or symplane ) front and rear of you put Symplane.

Don't use pressure because in this way the process is very slow.

OK, thank you. Why not use an outlet comprising both right and upper side?
