jamesearnest244 Posted October 12, 2020 Share Posted October 12, 2020 (edited) Hi, I'd like to ask if anyone has a methodology they can share for approaching small scale FLIP simulations. We all know FLIP has stability issues when working in the real-world scale of coffee cups and cereal bowls. But I haven't found any info that addresses directly how to get around that. If you scale the scene up by, say, 10, to get to units Houdini is more comfortable with, do you then need to: scale up gravity? Scale up collision velocity? Scale up Time Scale? I've read about the Spatial Scale setting in the Solver tab, but when I go by the documentation and set it to 0.01 (for a scene modeled in centimeters), I can't get even one frame simmed. IMHO since it's an exact scale of units, there must be a simple mathematical way to accomplish this in a couple of settings to get things to match up. Or am I wrong and it's going to take endless tweaking just to get things looking sorta right? I'd appreciate any input!

Atom Posted October 13, 2020 Share Posted October 13, 2020 I think that's what fluid particles can be used for. Check out Lewis' video and example file here. Quote Link to comment Share on other sites More sharing options...
jamesearnest244 Posted October 14, 2020 Author Share Posted October 14, 2020 Interesting, I'll give this a whirl on the weekend. Still I'm pretty sure there's a way to get around this issue with FLIP. I wonder... Quote Link to comment Share on other sites More sharing options...
berk_erdag Posted October 19, 2020 Share Posted October 19, 2020 Also maybe these Entagma tutorials might be of little help if you haven't seen them: https://www.youtube.com/watch?v=_6SQPc961ZE https://www.youtube.com/watch?v=HcBxUj4yGQ4&t=13s Quote Link to comment Share on other sites More sharing options...
