Mean shear rate = {yes | no}

Description / Usage#

The mean shear rate is defined as

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.
