Default different of WS in X direction and WSX
Posts: n/a
I wanna calculate the shear stress in x direction on a object in fluid domain. In the CFX post Function calculator, I found there are two choice: 1. areaInt, Wall shear, in global x direction, 2. areaInt, Wall shear x, none direction.

Which one should I use? I found the calculated values are different by these two method.
