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!

Greetings
Witold

Can you define a variable velocity.curl?

Wotild February 21, 2011 03:07
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!

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:
Quote:
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:
Code:
LIBRARY:
    VARIABLE: vorticity
        Output to Postprocessor = Yes
    END
END
(to find here: http://www.kxcad.net/ansys/ANSYS_CFX.../i1303200.html)
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.
