Hi, I’m working on a turbulent duct flow.
I used Gradient of Unstructured Data set filter on velocity vector then I checked the Compute QCriterion option and Compute Vorticity option. (as you can see below)
Finally, I used Contour to visualize the QCriterion. (as you can see)
The result can be seen in the following image ,but I think it’s not correct.
Where is the problem? Did I follow wrong procedures?
