Hi, I have the data after a simulation I ran in Fluent and now I am doing postprocessing in CFD-Post 2023 R2, I want to represent the shear rate inside the tube but I do not see the shear rate in the variables to represent I see the velocity the wall-shear (with their components x,y,z) and pressure. I thought I had to write a formula for the shear rate but till now I do not know how to do it, can someone help give me tips on how I can do so?

Hi, in Fluent select File->Export to CFD-Post and choose the variables you want to export. The Strain Rate will be in the list. For more information see the online help
