Fluent results
 
Hi!

On analyzing a 3D wing in fluent, it gave me the following results for force
1. Upward for on the top surface of the wing : 111N
2. Upward force on the bottom surface of the wing : -51N

Net result: 60 N lifts!
Why am i getting a negative lift for the lower surface??:confused:

Conditions:
Angle of attack = 8degress
Boundary conditions: Velocity inlet at 15m/s, outflow.. wing=wall. other walls = symmetry
