Tau Shear.
 

Is there any option to graph Tau Shear against distance? I'm looking into using the momentum equation. That is to say momentum change. I've drawn a control volume around my airfoil and the only thing I'm missing is the Tau Shear. Does anyone know if it can be graphed in FLUENT? I've looked and all I found was wall shear. Any help would be greatly appreciated.
Thanks in advance.
