Hi all,

How do you display the wing tip vortices?

I am using ANSYS 12 workbench. fluent to run simulation.

Set up: Homogeneous wing, symmetrical aerofoil, Angle of attack = 10degrees. inviscid.

I heard about isosufaces, q-criterion, lambda2? i cannot find any tutorials relating to this problem. I hope someone can help me.

if you would like details of the full set up and mesh, please ask.

thanks

Nathan

You could look at the rotation of the flow: Nabla_x_V
The vector product of Nabla with Velocity
