Schematic Link feature - Seeking sample model
I can't get the Schematic Link feature to work. I'm watched the 2 videos that exist showing how to connect a coax harness to a MoM modeled edge trace but the videos do not show the details of the MoM model. Is there a step-by-step for Schematic Link? Or can someone send me a sample of a working model? Thank you very much!

Regarding the post-processing issues of EDEM
Hello, the particle size I simulated is relatively small, so I may notbe able to see the particles clearly on the post-processing interface. Therefore, I would like to inquire if there is a way to enlarge and display the particles so that I can better observe their state. The version I am using is EDEM2024 Thank you!
