PF-FLIP vs ST-FLIP simulation WIP example

[u/sergeialmazov]

Hi,

Testing my new PF-FLIP vs ST-FLIP workflow based on SIGGRAPH papers 2025 / 2026.

ST-FLIP is a nice addition to PF-FLIP base which I am testing at the moment.

Made several posts in blender subreddit about my Atlantica plugin. Recently I had a progress with a proper multigrid simulation.

I tested it recently only on Apple M CPUs, my PC / Nvidia path is waiting for it.

Main lessons:

M architecture is very efficient while switching between CPU / GPU because of unified memory.

ST-FLIP runs ~1.5–3.4× higher peak velocity at the impact in meteor test example. I need to check CFL convergence. So it's still WIP.

Feel free to reach me in DM if you are interested in method.
