[Paraview] vortex core extraction

[Marzio Sala]

Hi All,

I am working on visualization for 3D CFD problems. The code gives me
velocity and vorticity components, and I am trying to extract "important"
features from the flow field.

Does anybody know if vortex core extraction methods are available for
ParaView? I am thinking to do something like the so-called lambda-2 method,
but other methods are ok as well...

Thanks a lot for your help,
-Marzio
