n PFC can I assign two different contact model to “ball-ball” and “Pebble-Pebble” and If possible how.
Hello @ShivamPandey,
Yes you can assign different contact models to different contact types. You would need to use the “type” keyword in the cmat such as type "ball-ball" or type "pebble-pebble". And example can be found here:
