Stress Contours#

Stress contours = {yes | no}

Description / Usage#

This card allows the user to invoke the components of the stress tensor for all viscoelastic modes be included as nodal post-processing variables. Often times this is not desirable on long time-dependent runs because of the voluminous data that will appear in the output EXODUS II file. This variable is called csij_mode in the output EXODUS II file, where i and j indicate components of the stress tensor and mode indicates the desired viscoelastic mode; for example, cs23_4 represents the stress contour for the fifth mode of polymer stress component yz.

The permissible values for this postprocessing option are:


Calculate and include the stress-tensor components for all modes of viscoelasticity.


Do not calculate and include the stress-tensor components.

These stresses become dependent variables if the Polymer Constitutive Equation card is given any model but the NOPOLYMER model.


An example card requesting viscoelastic stress components be written:

Stress contours = yes
