How can I prevent unwanted bonds between separately generated stems when using Bonding V2 in the EDE
Hello everyone, I am currently developing an API-based stem generation workflow in Altair EDEM and I am using Bonding V2 to create bonded stems (meta-particle-like chains made of segments and knots). My stems are generated programmatically during the simulation using a factory-style approach. Each stem consists of multiple…

Question about a post regarding MotionView coupling with EDEM and Inspire in the community.
This post explains using Inspire to parameterize the geometry, then importing the parameterized model into EDEM, and finally coupling it with HyperStudy. I understand all the steps up to this point. However, I’m confused about the part where the parameterized geometry is imported into EDEM and then coupled with MotionView.…

Is there any way to parameterize the geometry in EDEM and then couple it with HyperStudy?
I am currently conducting research on the chamber profile of a crusher. I want to parameterize the geometry that comes into contact with particles, and then investigate the relationship between the geometry under different parameters and the production output. However, I haven’t found where to parameterize the geometry in…

Impact velocity of particle–wall collision in EDEM?
Hi everyone, I have a question regarding particle–wall interactions in EDEM. When a particle collides with a wall, is it possible to directly obtain or calculate the impact velocity (i.e., the particle velocity at the moment of contact with the wall) within EDEM? Any guidance or suggestions would be greatly appreciated.…
