Below are some images of the vorticity that is generated by the wing. The first image shows the vorticity at the wingtip and the level is made clear in the wake region behind the wing. This image was generated on a very fine mesh of over one million cells. The second image was generated on a less fine mesh (clear because of the coarseness seen in the color of the vorticity) but this one also shows the Q Criterion at a level of .001 so we can see the vorticity present on the wing. You can compare the large region of vorticity at the wingtip to the relatively small regions on the wing surface. Again you can also see the vorticity existing in the wake region behind the wing at the trailing edge near the tip.
