How to enable or disable geometries in EDEM

Hi experts,

I was trying to find a way to enable or disable geometries at any time in the simulation in EDEM. Is this possible?

Ex. I want the one blade to disappear in a mixer, maybe after 4 seconds.

Thank you.

    Hi,

    If you know the time you want the blade to disappear at you can set a kinematic to ;'jump' the blade out the way.

    For example if you are running at a time-step of 1e-6 s you can set a linear translation kinematic with velocity of 1e7 m/s. This way it would move 10 m in 1 time-step which would make it jump out the domain without contacting any particles on the way. It would be best to add an end time to the motion, e.g. start at 4 s end at 4+1e-6 s to avoid calculating the motion of this any further.

    Otherwise the best approach would be to stop the simulation and modify the geometry properties to make it virtual.


    Regards
