Would any one know how to resolve this error message: Errors were encountered in CFX command language for this run: Error: Sub-object of type Variable not allowed in ROOT at line 0: I was trying to obtain vorticity out of a simulation following the VARIABLE file in /etc/5.6

I think you did as follows:

VARIABLE: vorticity

Output to Postprocessor = Yes

END

LIBRARY:

...

END

FLOW:

...

END

which will not work because VARIABLE objects belong to the library..Look at the top of the variable file (after the comments).. Try the following:

LIBRARY:

...

VARIABLE: vorticity

Output to Postprocessor = Yes

END

END

Hope it helps,

Thanks Juan, I got it now.
