Particles in container penetrating through wall

[JuhaHo]

I wonder what would be the correct way to make sure, that particles are not penetrating through container walls. Is it particle type issue or is there certain parameter?

You can try enabling CCD in the tyFlow > PhysX rollout, however that's not guaranteed to solve the problem when using Mesh mode in the PhysX Collision operator. The ideal collision mode for colliders is convex hull mode, but you'll need to make sure your container is split up into convex parts first (and that each convex part as a reasonable amount of thickness in order to form a proper hull). Perhaps it already is - you didn't post a screenshot of what the actual result looks like so it's impossible to tell.

Thanks, I tested that. I didn't see much change. I'm now increasing substeps.

I cannot post any screenshots on actual geometry due to NDA.
