Hi Guys, Please could someone tell me how to turn on the output of vorticity into the CFX5 results file.

I have read that you need to put this into the CCL:

LIBRARY:

VARIABLE: vorticity

Output to Postprocessor = Yes

END

END

but can't work out how to do this.

Hi,

I assume you know how to edit the CCL for a run. If it doesn't work for you by editting the CCL, edit the VARIABLES file in the <CFXROOT>/etc directory. Make sure you keep a copy of the original file as if you stuff the VARIABLES file CFX will not run correctly!

Hi Glenn,

Is there any default variable defined as "vorticity" in CFX Post 5.7? I can't find it while trying to plot the contour of vorticity. Should we define it ourselves? Thanks for help.

I have edited the VARIABLES file in the /etc directory and it seems to work. Could you tell me how to edit the CCL for just the run itself. I have tried reading the variable command as per my initial post via the CCL import but just get error messages. I'm not sure what i'm doing wrong. I know how to put expressions into CCL but not extra commands. Is the editing of the CCL for extra variable done in pre or solve!

Many Thanks

Hi,

You should be able to put the CCL in using Pre or the solver, but I don't know the exact syntax. Hopefully somebody on the forum will know, otherwise contact your support rep.

Hi Pete,

If you did not edit the VARIABLES file or add the CCL to include it then the only way is to calculate it yourself in CFX-Post.
