Viscous Stress#

Viscous Stress = {yes | no}

Description / Usage#

The Viscous Stress tensor. Output VS11..VS33

The permissible values for this postprocessing option are:

yes

Calculate the viscous stress

no

Do not calculate the viscous stress

Examples#

Following is a sample card:

Viscous Stress = yes

Technical Discussion#

Calculates the viscous stress tensor:

\[\sigma = \mu \left( \nabla u + \nabla u^T \right)\]

where \(\mu\) is the dynamic viscosity of the fluid.
