How to define "shear" rate in CFD-Post?
 

Hi there,
I was just wondering how to define the magnitude of "shear" rate in CFD-Post. I found that "strain" rate is already available in CFD-Post, but I need to solely take "shear" rate as "shear" rate is just one part of "strain" rate. Is there anyone who knows what actual expression I have to enter to define the shear rate in CFD-Post? or is there anyway to directly use the shear rate if it's already available in CFD-Post?

Thank you very much for your help!

It must be in data file quantities. You need to select it before starting your simulation.

The one in the data file quantities is "strain" rate rather than "shear" rate. Do I need to define shear rate based on its mathematical definition?
