I need to recreate this effect for a client, I am new to Tyflow so need to know roughly what to do. I know it follows a path but changes to fill the void and create a vortex.

PLEASE ANYONE. I AM REALLY NEEDING HELP.

For fluids you'd typically want to use a dedicated FLIP solver, like PhoenixFD. tyFlow doesn't have its own FLIP solver.
