Hey there, I've encountered imo strange behaviour with my flip Sim. I got Liquid running down stairs. The Liquid should be a bit viscous so I introduced the attribute on SOP Level. For the collider I used volume collisions and a pretty high-res (.002 voxel soze on a 5m Stair) VDB to which I am pointing in my Static Object. When I simulated the liquid with f.e. 100000 viscosity (I tried values from low to super high) its just behaving like water. As soon as I decrease the resolution of my collider it works as expected, or If I increase the resolution of my Flip Sim while leaving the high-res collider as it is it also works as expected. My Question would be: Is there a dependecy between the resolution of the collider and the fluid? does a low res fluid not work properly with a high-res collider? I thought the more resolution on my collider (not too much to keep it efficient) the better. But it seems like that is causing issues -- in my case the solver ignoring the viscosity and the fluid splashing like water while showing correct viscosity values in the GEO Spreadsheet... Thanks in advance and stay safe!

Hey guys, Is there a simple way to disable some particles from the simulation like i'd do with RBD? I have a set of particles inside a group and I need them to be stopped at same position but still interacting with the other particles. Does it makes sense? The group is animated I tried setting v=0 but it doesnt work as expected. I did another trick inside a sop solver to get the position from the previews frame so it stays static but then I cant use the resample. Im just wondering if theres a a simple way like like an attribute the would make them sleep. Cheers, Alvaro

Hello, I am dealing with a particle sim and I need some way of optimizing it. This is the case: particles are emitted and falling on the ground. Once they fall on the ground they bounce a bit and then stop moving. In this simulation I need to emit a lot of particles so it goes slow after a bit as particles accumulate fast on the ground. However I don't need to simulate those particles on the ground anymore, but pop solver simulates them all. Is there some sort of equivalent of @active attribute as in bullet sim? I can think of one way - I can set up a velocity treshold, which will move stopped particles to a group. Then I can remove particles from this group so that pop solver doesn't simulate them, but before that I will collect them in another solver? Any better approaches / ideas? Juraj
