Calculation formula for particle collision energy
I would like to know what is the calculation formula for particle collision energy within the EDEM system? How can I obtain the collision energy of particles - particles and particles - walls? What should I do in post-processing analyst?

Hi Yudong,
You can find the equation used to calculate the collision energy in the EDEM documentation. It's in EDEM Simulator > Simulator Settings > Collisions (CPU only). You can find the documentation here: https://help.altair.com/edem/Simulator.htm
In order for you to analyze the collision energies, you must enable the Track Collision option in the Simulator. Keep in mind that if you enable this option you'll have to run your simulation using the CPU.

Dear Renan,
Thanks for your reply.
I also have a question, when I analyse the collision bewteen particles and geometry(wall) in Histogram, the normal energy loss is nagetive, but tangential one is positive. So, I have no idea why the value is nagetive?
Thank you very much.
