  Hey Guys,nI?m new here and I have a problem. I want to calculate the shear stress of the fluid in a pipe and not on the wall. How can I do this. nThanks, if you have any ideas or answers.n

  Fluent provides you the velocity gradients as well as the strain rate you can code it on your ownn

  It's a function of strain rate, velocity gradients and viscosity so use a Custom Field Function or UDF and dump the value to a User Memory. n
