Hi,
I have problems with the overlapcheck using liggghts 3.3.1. I would like to get particles without any force or velocity, but when I'm creating the particles they overlap and have a big kinetic energy. I use this command:
fix ins5 nve_group insert/pack seed ${seed} distributiontemplate pdd5 maxattempt 200 insert_every once overlapcheck yes all_in yes vel constant 0. 0. 0. region pi particles_in_region ${nliggghts_CB}
I attached my code. Maybe someone has an idea what's wrong.
Regards,
Laura

Do you see like an explosion
Do you see like an explosion in the post-processing? maybe you should check the timestep. If you have a wrong timestep (high), the particles will overlap with each other and as a result, they will "explode" (high overlap). Try setting the script with a lower timestep (for example if you have 0.01, try with 0.001 or 0.0001. That will affect in the simulation calculations).
