# Mean Shear Rate#

Mean shear rate = {yes | no}


## Description / Usage#

The mean shear rate is defined as

where $$II_D$$ is the second invariant of D, the strain-rate tensor,

associated with the Navier-Stokes equations. This variable is called SHEAR in the output EXODUS II file.

The permissible values for this postprocessing option are:

 yes Calculate the mean shear rate. no Do not calculate the mean shear rate.
