Turn on variable vorticity after solving
Hello all!
I searched in here and in google but only found how to activate the vorticity variable in a CCL file. My problem: I did the solving already (results were weeks of computer abstinence). But afterwards I need to use the variable "vorticity", which is not listed in the variable list. Is there any way to activate it without making the calculations again? I am using ANSYS CFX 12.
Thank you a lot for helping!

Can you define a variable velocity.curl?

Wotild February 21, 2011 04:07

Yes, velocity.curl (for each direction) is in the list.
Is there a proportionality between them?

You should be able to answer that yourself - look up a CFD text book for the definition of vorticity.

Hello Glenn,

thank you for your "motivation". After I looked up the definition it still was not clear to me. I could not image one and the same thing to have two names. But Ok, vorticity and velocity.curl are of course the same.

Thank you!

@ Witold
What do you exactly mean by "how to activate the vorticity variable in a CCL file" .

Am sorry but I didn't get you.

What do you actually want to find out ?????

By "activating it in the CCL file", I meant:

Note that the vorticity has to be activated in order to be available in ANSYS CFX-Post. The following lines are to be added to the solver CCL:

    VARIABLE: vorticity
        Output to Postprocessor = Yes

(to find here:
I wanted to have the variable "vorticity" listed in ANSYS POST. But as I found out (with some help ;) ) vorticity and velocity.curl are the same things. So my question ist answered.
