Calculating the Wall Shear Stress Gradient over surface
 
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.

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

Thank you
