  Hi all,
  
  Does anyone knows how to effectively view Iso-surface of Vorticity (like Q-Criterion) in ANSYS Fluent.
  
  I have flow going through 4 vanes with casing at outer periphery, how do I visualize the vorticity in the flow?
  
  Is there an input that I can use?
  
  Thanks.

  There's a vorticity magnitude available under the velocity contours, does that solve the problem?

  Hi Rwoolhou,
  
  Thanks for replying. I used Q-Criterion from Custom Function with a constant value. It looks fine for a particular instantaneous time-step.
  
  Will look into your suggestion.

    Hi jlhee,
    I am going to create exactly the same contour.
    How can I do this?
    I will be grateful if you provide me with an educational video.
