Drops splash on collision

Postby Sanka » Wed Jul 06, 2016 7:27 am

Does anybody know how to create these real rain splashes once they hit the ground. My scene looks like here https://www.dropbox.com/s/2n55cdm8e7cdi ... 0.png?dl=0 it's all great, there is some surface tension, and force drag and drops look nice but they don't interact once they hit the plane. It just doesn't much behave as a liquid. I've seen recently this awesome video from Realflow and it's actually exactly what I need to achieve. Can anybody reveal how to build scene like in this video https://vimeo.com/169120250 or what am I doing wrong?

BTW, I've also tried dyverso emitter but it crashes all the time with error of insufficient memory or something.

Many thanks for help!

Here is a project file (RF2015 standard version, 80MB) for something similar, using the standard particles. Initial states are included. Maybe it is a starting point for your project.

Christian, do you know what to do about the crashing when simulating with dyverso emitter by any chance? It happens on the 10-20 frames. It's jamming RAM memory and it never happens with SPH. I don't understand why does it need that much of a memory. I tried to increase and decrease the substeps, I tried to run the command line with which RF btw crashes rightway on the first frame. Thanks

Crashes and hangs can have many reasons, including the GPU and drivers in this case.

Best is to submit this via the Nextlimit customer gateway, including the scene file.
