How to model particle deformation & internal damping via overlap in EDEM?
Hi, I have a question regarding Altair EDEM settings.
I'm trying to model a situation where particles deform upon collision, and I want to express that deformation through actual penetration (overlap) between particles.
In addition, I’d like the particles to have internal damping, so they absorb impact and return slowly, like viscoelastic PU beads.
To achieve this kind of behavior, could anyone advise:
- Which Base Model and Friction Model should be selected in the Physics tab?
- Are there any Additional Models that should be activated to support this behavior?
I'm using ~2–4 mm diameter viscoelastic (PU-like) particles. Any insight would be much appreciated!
