How does ANSYS calculate stress along a defined path
 
2 Attachment(s)
I am trying to do a Boundary condition check on my structure.

I am analyzing shear/normal stress on the middle fiber at the center of the structure.(5th row from top or bottom at the center)

I defined a path along the left edge of the middle fiber, just bordering the gap, and mapped shear stress onto it. However, when I plot the graph, I do not get ZERO shear along that edge as expected. Am just wondering how ANSYS is calculating the stress and how it is interpolated.
I have attached some graphs. Any help would be greatly appreciated.

Thanks,
Akoth
