how to calculate vorticity?

April 12, 2005, 23:06

recently I model a case involving in rotating flow field I want to calculate the vorticity in a specified location or specified cell set. how can I do? thank for help

There is an option in the oper command to calculate curl. It only works on vertex data though, so to get the curl of the velocity vector:

getv all oper curl n 1

We know vorticity is curl of velocity vector. I want to know what is the effect of each component of velocity on vorticity. What does it mean by positive value of vorticity and negative value of vorticity ?
