Hello,

I'm sorry if its a silly question, but I'm wondering does anyone know is there a way to find the wall shear stress gradient over a surface in Fluent as I haven't found any?
I am looking to find the wall shear stress gradient alone a particular line straight through this surface (as it changes along x), I have created a plane and obtained the values for wall shear stress all along this line, is it just a case of dividing these shear stress values by their x coordinate to get the gradient?

All help much appreciated!

Thank you in advance

Hi,
Do you find any answer for this?
I found out that there are different way to calculate the WSS for 2D and 3D case.
calculate y+ and u+ -how to get wall shear stress?

Im not really understand. If find out out anything about this, can you let me know?

Thank you

Regards,
Naimah
