Hi Everyone,
Recently, I have been using EDEM to simulate the process of a cotton fiber falling from a height and landing on the ground, but I have encountered some issues. The cotton fiber rebounds too high upon hitting the ground, and it also breaks apart during the collision with the ground. The cotton fiber model is composed of spherical and cylindrical particles connected end-to-end, and the particles are linked using the Bonding V2 model. My understanding of the Bonding V2 model is that as long as the forces between the particles do not exceed the normal strength and shear strength, the fiber should not break. However, no matter how much I increase the normal strength and shear strength, the fiber still breaks. Do you have any good suggestions?
Best regards,
Bai
