Volume Loss in FLIP SIM? Grid Scale and Particle Radius Scale
When working with FLIP we must remember that we are working with both particles AND volumes. It's important to find a balance between speed and quality and the particle radius scale can help the balance of quality while maintaining the speed.
As always comments are appreciated. Let me know if there's anything else that you think would be useful to record!

Thanks! There is also "Apply Particle Separation" under "Particle Motion" that helped me reduce the volume loss on a small scale scenario.
Exactly what I needed. Thank you!
Very nice and informative video! keep up the good work
You have saved my day ! Thank you :)
You made my day! Thanks!
Hey thanks for this! Helped a lot!
Thanks a lot Janks! Super useful
Brilliant! Thank you!
Very informative and very helpful. I have been trying to keep a volume of water in a bucket, but keep the processing low as I have an old PC. This might do the trick! Thank you!
Thanks! Super useful info.
Thank you very much. It's also very interesting that they have bad numbers by default.
Thank you!! First coming into Houdini I found volume loss to be super frustrating and time consuming to figure out but grid scale + particle radius scale adjustments seem to be doing the trick now

Awesome! So glad to hear! I used to have this problem a lot too and I saw there were 0 tips on how to fix it.
Brilliant thanks for bring up
Thanks a lot!
good work john. I want to learn too. Everytime you with the pointer you should say where you are clicking.

hey amazing video! Im getting this problem with the new Flip SOP setup that was implemented in houdini 19.5, I lose fluid / volume and tweaking the grid scale / particle separation doesnt fix it. Unfortunately particle radius scale isnt exposed in the flip sop setup so not sure how to solve this, but ill try the regular dop way that you are using

in 19.5 I've found that turning on "enforce particle separation" fixed it for me. It's in the flipSolver under the Fluid behaviour Tab. I also set the grid scale to 1.5 (flipContainer). Also, just FYI i left the other particle separation checkbox off in the setup tab

@@_incendiary i use H19.5.493 (apprentice version btw) and I dont have the "enforce particle seperation" option? My sim is still losing so much volume Do you know where else I can find it?
