what does Iso-Surface mean in tecplot?what does it show?
Is there anyone who knows how they plot these vortical structures in double bends?
thanks

For plotting vortical structures there are several ways you can use:

Vorticity, Lambda2 and Q-Criteron are the most common ones. Search on Wikipedia for more information.

Just choose those parameters on isosurface with an adequate isovalue until you can see the vortices you expect.

Hi there are several articles on vortex topology at the links below:

Q-criteria macro

Also I have a white paper I can share with you if you are interested. It was too big to upload on with the post.

I found the link to the white paper on the subject, but I can't locate the webinar that Scott Imlay and I presented on Lambda2 and Q.
