Particles disappear

bruno75

Hi,
I am doing a simulation of a ramp that vibrates and has particles. The issue I am having is that when the ramp starts to vibrate, after 0.05s the particles disappear. I have tried reducing the Rayleigh Timestep/ Percentage, but this keeps happening. Is there any other reason why particles might be disappearing and how to fix it?

Hi bruno75

What is the percentage that you are using? The general recommendation is to use 20%.

Also, particles could disappear if they go out of the environment domain (red box). EDEM does its calculation only for particles within the domain, and deletes all particles exiting the domain. You can consider enlarging the environment domain, to check if that helps.

Thanks,
