Visualizing Wake using Vortex Core Derived Part
 

Im trying to vizualise the wake.

Using the vorticity field function, I can see that there are areas of high vorticity.

But when I used derived part "Vortex Core" to visualise the vortex cores, I do not see anything when I select the "Vortex Core" derived part. I used the Geometry scene.

Can someone who knows help? Thanks!

anyone has any working examples on iso-surfaces or vortex derived part?
