I am working on post processing the results for stage 2 of a rocket. The area I am interested in is the purge ring inside stage 2. The ring has multiple holes that blow onto a tank. I need to animate the iso-surfaces from the purge holes to show the flow hitting the internal LOX tank. Is there a way to make an animation that looks similar to the vorticity confinement simulations (smoke/ fluid flow that moves and dissipates)? Is it even possible to animate iso-surfaces by changing the velocity contour values?
