Hi, dear everyone!
I am conducting a DEM simulation of drum granulation behavior. However, as the computation progresses, I noticed a significant reduction in the number of smaller-sized particles. I have tried the default solver, SMP solver, and DPM solver, but this phenomenon persists. Additionally, I’m using a Linux system(24.4.1) and have included the case files in the attachment. I hope this issue can be resolved with your assistance. Thank you very much!

Please double-check the files you attached. The .mfx file says it was created with 24.2.2. The STL normal vectors are pointing in the wrong direction.
You can try increasing the spring stiffness to see if it helps.
