Hello

I'm trying to plot the shear stress and resulting skin-friction coefficient from my Fluent files.
Are the variables 'Wall shear-1' , 'Wall-shear-2' and 'Wall shear-3' shown in Tecplot the same as the 'X-wall shear stress' 'Y-wall shear stress' and 'Z-wall shear stress' shown in Fluent.

When I compare Tecplot with Fluent they are not the same, both the contours and the range of the variables.

Do I need to calculate the wall shear stresses through a user function?

Hello
I have tried another method to calculate the wall shear stresses within Tecplot, but I am still not getting comparable results with the same variable post-processed in Fluent.

Does anybody know if the variables 'Wall shear-1', 'Wall shear-2' and 'Wall shear-3' that are shown when native Fluent files are imported are forces?

I tried to calculate the stresses based on theory using the formula shown in the attached image file.

I follow the definition of the variables and general method as per this link
https://kb.tecplot.com/2018/02/23/ca...orces-moments/

However, in this link the forces are calculated using the equation in the second attachment.

I stop at the stresses. But, I still get different variable ranges and contours when I compare with Fluent.

The steps in the link are the same that I also used. I just found the link later.
