Liquid bridge contact model for wet bulk material
Hi, I just found the Liquid Bridge contact model as a new contact model in Altair EDEM 2025. I assumed it could handle the cohesive/sticky material caused by the water content percentage. Is it correct? And what is the difference if we use the JKR contact model rather than this new contact model? Thanks in advance for any…

How to achieve a correct penetration depth when working with contacts in motionview?
I am trying to create a contact model for an opening hinge. The purpose is to get force reactions on the fixed constraint (later bolt group) that holds the hinge. The hinge is actuated by a Torsion spring (Spring Mass Damper in MotionView) with preload of 90 deg and KT = 0.05 I have simplified the hinge just to the contact…
