Shah Akib Sarwar Member Shah Akib Sarwar Join Date: Mar 2021 Posts: 41 Rep Power: 5	Can somebody please explain the difference between elasticity coefficient and restitution coefficient in patchInteractionModel (standardWallInteraction or localInteraction) for rebound? By my understanding, the restitution coefficient itself represents the elasticity in a collision between a patch and a particle. I looked at the source code, but couldn't understand it properly, If somebody has some documentation for the source code, I'll be really grateful. Thank you, Akib
