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:

yes	Calculate and include the stress-tensor components for all modes of viscoelasticity.
no	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.

Examples

An example card requesting viscoelastic stress components be written:

Stress contours = yes
