Vorticity Vector#

Vorticity Vector = {yes | no}

Description / Usage#

This option allows the user to output the vorticity vector to the output EXODUS II file. It applies to problems with the fluid momentum equations (see EQ = momentum* cards). The output nodal variables are named VORTX, VORTY, VORTZ.

The permissible values for this postprocessing option are:


Calculate the vorticity vectors and store in the output EXODUS II file.


Do not calculate the vorticity vectors.


This example card requests that vorticity vectors be written to the EXODUS II file:

Vorticity Vector = yes

Technical Discussion#

The vorticity vector function, \(\underline\omega\) , is defined in terms of the velocity \(\underline\upsilon\) as:
