How may I show vortex in CFX?
 

Hello
I'm doing my internship and I'm about to show vortex core region. How can I do?
and what different criterion mean (absolute helicity, eigen helicity, lambda 2 criterion, ....)
What have I to choose?

Thank you

Benjamin

I think there is a CFD-Post variable designed to find vortex cores - have a look in the tutorials or the CFD-Post documentation.

I did it, but it's just definition of each variable

Sounds like a trip to the library is required. That, or some fancy googling.

Benjamin, I agree with you that the manual is very limited, as it is for many topics. I do not believe there is a tutorial on the topic either. I will respond if I find anything, as I am interested in this as well. Good luck!

Benjamin,

There is a tutorial at http://www1.ansys.com/customer/conte...uent/flcfd.pdf

This looks promising. Check out Step 10.

I would be very interested in anything that you might find as well.
