Vorticity field and Q-criterion LES simulation

[marciafof]

Hello,

I am working on LES simulations of the urban boundary layer and I would like to analyze the turbulence structures using the vorticity field and the Q-criterion (Hunt et al. 1988). I know I can do this with Paraview but I would like to avoid doing this step in the post processing.
How can I add these variables to the calculated fields? Is there any flag in the source code that I can activate ?
I am using version 6.0.

Thank you in advance,

Marcia

Hello,

Yes, there is an option, though it is not in the most logical place in the documentation so a it hard to find...

Search for Q_CRITERION in the following page to see how to activate it:

Best regards,
