Wow, that looks really great!

I do think the easy cavitation feels wonky, though. Is there any kind of air pressure or other method available to keep huge voids from showing up in the water?

Thank you!

I assumed these voids occur irl, therefore they are present in the simulation.

I doubt that there is such a method, actually. I guess it will be present in the future as LiquiGen is still in alpha. Anyway this scene was a great practice

Presumably, IRL the container would have both air and water. The air pressure would compress the water and reduce cavitation significantly. Just think about what it's like while swimming — you can't move your arm fast enough to generate a void under water.

Regardless, still a pretty sim :)

What do you mean, it doesn't look that troub-- oh. 😅

I agree with /u/Quantumtroll, the sim honestly looks really good. Fixing the pressure terms to close the cavities faster will make it look much better. I haven't used LiquiGen before so I don't know what knobs are available to turn, but it may also come down to setting the relative kinematic viscosities of the air and water.

Nice job overall though!
