Hi, I am trying to do powder compaction using Hertz-Mindlin contact force and JKR adhesion model and I have a few issues.

1- so in image 1 you can see there is a cylinder coming down to compress the particles, in image 2, when the compaction is happening particles goes inside the solid boundaries. can you please explain why this is happening ?

2-in image 3, after the cylinder goes back up the particles go back to their original orientation and does not remain compacted, what should i do tp avoid that?

Thank you for your help.
