Hi everyone,

I would like to understand which scalar has been used to color the vorticity isosurfaces in these pictures. Some descriptions (not these) mention the streamwise or spanwise component of vorticity. Non of them (Vorticity_Y for instance) give me the same in Paraview. What surprise me the most is how the vorticity color melts with the object's one.

Bonus question: is there any relevant scalar which might be used to color QQ or Lambda2 as well?

Thanks!
