I can not find voricity or curl variables in post processing

raminostadi · September 14, 2016, 02:52

Hello experts.
I want to see vorticity in ansys-fluent-post processing, but when I want to

define vorticity or curl of velocity as a variable in results,I dont have them because I just have ''gradient'' in my variable defintion.

maybe I should create vorticity in fluent setup.
please help me,

How to define vorticity in fluent( setup or post processing) and where to define vorticity؟

If you want to postprocess in Fluent, it is very easy:

-> Graphics and animations
-> Contours
-> Contours of: velocity
-> X-Vorticity (or Y-vorticity or Z-vorticity)

If you want to do in CFD-post, you have to save the vorticity in Fluent:
-> File
-> Data file quantities
-> Additional quantities
-> X-vorticity, Y-vorticity and Z-vorticity

Good luck!

Thank you so much.
It is very helpful and I can add vorticity.
