Vorticity
 

Hallo Is there an option in CFX 11 post to visualize and extract vorticity in the flow field?

Turn in on under Trasient Results

Thks,I have seen it.

But is it not possible from CFX-post? I define the vorticity(only 1 component for 2d flow) For the transient simulation ,at all time steps this value is the same.Is this possible,or simply I cannot create such expressions in CFX post for transient case?

Re: Vorticity
 

Vorticity is not written to the .res file by default. You need to enable it, you need to include the following CCL:

LIBRARY: VARIABLE: vorticity

Output to Postprocessor = Yes END END

You could run your current .res file for one iteration with this CCL to generate the vorticiy.

Thks for the replies

I have a transient simulation of 2000 time steps.
