How to increase substeps without affecting viscosity?

Post by thelastviking » Sun Apr 12, 2020 11:42 am

Hi guys, beginner question here.

I find that in general my DY sims always look best with around 5 substeps while testing. There always comes a time though when I need to increase the value to get rid of stepping from the emitters or deal with fast moving liquid. I find that as soon as I increase the substeps past 10, the liquid becomes way too viscous and I lose all the splashes.

Is there something I can do to counteract this and still have higher substeps? Thanks a lot.

Hi

that may depend on what kind of liquid you want to simulate. If it should represent a watery liquid, I choose the "Liquid-SPH"-type in the Dyverso domain. That corresponds to the classic solver and does not get more viscous with changes in substeps.

Wow, totally solved. I wish I'd known that a long time ago, thank you! I always stuck with PBD because I couldn't see any differences other than sim speed. Very good to know. :D
