Activate vorticity
 
Hi, all,

I want to activate Vorticity in CFX Post to help analysis. But problems came out.
An erroe message,
"CCLAPI::validateData - CCL validation failed with message:
Error: The essential parameter 'Option' is missing from /LIBRARY/VARIABLE:vorticity ",
displayed when I add the section below into Library.
VARIABLE: vorticity
Output to Postprocessor = Yes
END

Alternatively, I selected the variable Vorticity in output control. After 1 iteration, I run the CFX Post to visualize the vorticity contour. But an other error came out, which says,"DataReader::loadData - Error reading file 'D:\run_001.res': Error reading dataset G/COMMANDS"
Why these happened?

I know editing the VARIABLES file in the root directory is an efficient way, but I want to know why the two errors took place.

Please do me a favor to explain. Many thanks to all of you.

Vorticity can be calculated in CFD-post, see Variables/Derived/Vortex Core/Velocity.Curl

Dear Lance,


Thanks for your reply. I did your comment and the result became like the attached. I want to know is it correct? or the vorticity should be reciprocal across the breadth of the ship?


Best Regards
