Tutorial: Crown Splash From Scratch (Patreon)

Hi Everyone!

In this tutorial I show you how to setup a crown splash from scratch with FLIP fluids in Houdini.  

I have made a few tutorials about small scale FLIP fluids and surface tension in the past but this has been requested a couple of times and even if you watched the other ones I think this is useful to get a better understanding of how to control your small scale simulations. 

I am switching over to YouTube for my video in an attempt to reach more viewer because it seems like that is where all the cool kids are these days :). Since it's my first time trying it I also uploaded to Vimeo as a back up.

Enjoy!

Hi! I find the Time Scale parameter really confusing. If I lower the value and scale the forces to match, I don't just get a slower sim, I get a completely different behavior. Just like when you lowered Time Scale at 14:21, it didn't just slow things down, it changed the behavior completely. I normally don't find that I get the same result as when increasing substeps. Is there anything else going on under the hood with this parameter?

Hi Amir! Yes time scale is confusion when working with FLIP, I could make a whole video just on that. When you change the timescale you should leave your force scales the same, so gravity stays -9.8 for example. Changing the timescale gives you different results to changing substep because not everything in the flip solver gets substepped when changing the substeps. You will also probably get different results when changing the global substeps on the DOP object.

Thanks, that clears up a lot. I appreciate it!
