Wall Shear Stress Sampling Probes
 

Hello all,

I think I am facing a quite easy problem, but I can't solve it myself.

I am simulation an airfoil and want to get the wall shear stress for x/c.

I am able to calculate the wall shear stress with the help of the standard utilities. So my first idea was to extract the wall shear stress values from paraFoam. But I couldn't figure out how to extract the values on specific points into a csv file.

My second idea was to use the sampledict. Which works fine for the pressure and the velocity at my defined points. however, I couldn't calculate the wallShearStress right away. I think I have to use the post utilities first, right?!

I want to get the wall shear stress for around 100 points.

any help is appreciated!

Thanks a lot :)
