  Hello, I wanted to calculate the shear stress in CFD-Post for Ansys Fluent [Polyflow Classic]
  
  My problem:
  I don't exactly understand how to apply the expression correctly, I want to know the shear stresses along the wall but I dont know where to find stress tensor or similar, any ideas? Do I need to specify already somewhere in Polyflow setup that it needs to be output to a file or am I just looking in the wrong spot?

  Hi,
  In CFD-Post, you can just select the wall zone and use local range to get the shear rate values on only the selected wall alone.
