how to get velocity gradient tensor with FLUENT
 

Hi,

I'm new to CFD. Now I'm working on the mixing effect of a specific mixer. I wanna use mixing index to characterize it and therefore need to identify velocity gradient tensor first. I went through the manual of FLUENT but found nothing about it. Any input is highly appreciated.

Cheers

Check Chap. 3.2.3, the part refering to gradients. You need to issue a TUI command to access the gradients of the calculated variables.
