Hi guys
How I can estimate turbulence intensity(TI) in fluent while I am using the LES model and plot it for a line?
Thank you in advance

Hello,

I believe you can create UDF's for the respective equations as found here: https://www.cfd-online.com/Wiki/Turbulence_intensity

There are many videos/written instructions online how to create a UDF, as here: https://www.youtube.com/watch?v=OPfgkORSESQ

Thank you so much, dear, I'm sorry for the delayed response you're recommend was helpful and I wrote a UDF to extract it.
