Re: Making foam in RFC4D using the filter daemon

Thanks ChriFF! I think I will go with the second option, the collision trigger. The vorticity is fine for splashes or for situations like a river going through some rapids. But the collision is more like what happens in reality with the one-time activation of the foam which calms and solidifies when...

Making foam in RFC4D using the filter daemon

Hi over the weekend I have played around with the filter daemon and Dyverso-SPH in RFC4D for making foam when liquid is poured inside a glass. It works well with two fluids and the transition depending on the filters properties. But you have to decide which event should be used for the transfer. I h...

Re: Hybrido deals with corners worse than standard particles?

To directly answer your question: Yes, hybrido (and dyverso) are indeed less good at filling small edges than standard particles and the main reason for that is simply the ability of the standard particles to make particle-polygon collisions while hybrido and dyverso replace polygon objects with vox...

Re: Pre-Simulate at a lower resolution?

Unfortunately, the resolution of the particles/cells is pretty much fundamental for the calculation of the fluid, so I don't know about effective methods to reduce that part. However, you can exclude additional features of the simulation in not-needed ares: the meshing can be limited to the area tha...

Re: Dyverso Granular experiment - Drop heavy object into sand?

https://youtu.be/Zb0h919dPTY

This example is with DY interaction factor on the rigid body=0.001
As you can see, the rigid body sinks in, but continues to spin around and to mess up the pile of mud/snow.

Re: Dyverso Granular experiment - Drop heavy object into sand?

My test https://youtu.be/NPINrT9AN64 Indeed it is a challenge to adapt the rigid body parameters here. On the side of the granular solver we have here a block of heavy snow or mud (kept in place by invisible frame around it) with cohesion. Without cohesion it would be sand. We see here that the rigi...

Re: Help with Foam without Krakatoa?.. no idea what to do

Try dropping some cubes into the sand and see it if explodes or works. Maybe throw me some settings if you get it to work. when i try it the cubes fly off or drop to the bottom.


Ok, I will test some conditions and report back.

Re: Help with Foam without Krakatoa?.. no idea what to do

Yeah, Krakato is a great point-renderer for such tasks. I have it for Cinema4D. But I am afraid that it is a declining product as Thinkbox/Amazon has not made advertising anymore for it and they have not yet decided if they will adapt their C4D-R20 plugin.... Regarding the situation in 3Dsmax I don'...

Re: GPU results? 1080?

Hi Oldcode you can use Dyverso solvers with or without the GPU-acceleration on. Best is a graphic-card with many computation cores and a decent amount of video RAM. The Dyverso system currently uses only one GPU at the time. I see here very nice speed increases with a good GPU and Dyverso in the sta...

Re: Troubleshooting bouncy edges

Hard to tell.... maybe some settings vary between the objects, or one of the objects has modeling flaws such as holes (collision volumes should be closed/watertight)? You can visualize the real voxe-shape of the collision volumes with this option "Show Collision Geometry" and then look at ...
