shear stress in a partition

      I have a tube in Fluent, and need to see shear stress in a cross-section of the tube (not all the wall). In other words, I need to partition the cylinder into small segments (sub-tubes) and see the shear stress contours in each segment. My model was made from mesh (not geometry). Any idea, how can I do that? 


      Thank you

      I'm not sure what you mean, but will an iso-surface do the job?  You may need to combine with a custom field function if you need an "odd" location/angle or non-planar surface.

       Thanks for your reply. 


      I need to see the shear stress in two regions shown in the picture below separately (not the whole cylinder):

      Fluent keep track of shear stress at walls. In a volume you need to reconstruct that by the available velocity derivatives

      I need to see shear stress in the wall but not the whole wall. I just need to see shear stress in the specified sections (in the wall). 


      Thanks

      Then try clip the wall.
