Manually select particles you want to remove (because of collision error)

[pastor]

I've already created some scene for other user.
It's not a coffee, but chunks filling the container, but you can replace it with coffee models.
Here it is:

Yeah, increasing substeps (both globally and in PhysX) can help make more stable simulations.
But, truth be told, I very rarely use it, because it just work with defaults as it should in most of the cases.
Only if I fracture particles to very small geometry pieces, I probably get some very bad models (2 vertex in space maybe), and then I need to increase sub-steps.

Thanks !!!!


While looking at your example, I figured I used too much operators in my simulation (particule physics , force and mass) so I removed them and the simulation looks faster !

I suppose the Phyx Collision (Mesh) operator is enough to manage the Inter particule collisions ?

But I don't understand why my grain particules are jittering at the end (they are continuously moving at the end of the simulation)
in the Particle Physics operators I removed, it seems that Collision force settings (stiffness / FRiction / Mass z-bias was helping to stabilize the jittering (but it was not perfect)
But in your example, it was not jittering at the end while your settings was pretty untouched
