DEMO / Flip Fluid Inside Torus Knot
Still have to find out how to make Flip Fluid smoother when inside inverted obstacle, and some fluids seem to dissipate unwantedly.
The setup is simple:
Bunch of fluids inside inverted Torus Knot obstacle. Then a simple icosphere obstacle that goes in around and looping along the path of Torus Knot to push the fluid.
