Hi, I have finished an analysis. it took long time. nearly 4000 iterations. so I selected 'standart variable list' in the Output Control section in CFX-Pre. now i am not seeing the ' vorticity variable' in CFX-Post. i needed create a variable that will calculate vorticities. so i defined a variable and used it. but it did not give reasonable results. Can any good human help me about that problem?

regards

cmete

Add the following CCL to your def file:

LIBRARY:

VARIABLE: vorticity

Output to Postprocessor = Yes

END END

You'll then need to run your case for one more iteration to get a new results file that includes this variable. Hope this helps, Mike

You could also go back to Pre and add Vorticity to the res file through the Output Control panel. Use the new def file with your existing Res file to initialize it and run it for one iteration. Pretty much does the same as the above.

If you always want vorticity to be output, edit the $CFX_ROOT/etc/VARIABLES file in a text editor. Search for "VARIABLE: vorticity" and change the "Output to Postprocessor" parameter from No to Yes. Subsequent runs (on machines linking to this installation) will always include vorticity.

Dear Sir,

Why you need "vorticity" and which it indicates.

Thank you

Dear robin,

I have done all of that but my results were come all in blue!!
whereas it was wind tunnel simulation I predict the wake vorticity must have been different

can you advise me what i should do?
