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).

I think you have the wrong
I think you have the wrong timestamp set in the command set you are using. If you set the time stamp incorrectly the particles will overlap and as a result they will "explode". Try setting the script with a lower timestamp (e.g. if you have 0.01, try with 0.001. flappy bird

The timestamp you are using
The timestamp you are using in the command set seems incorrect. Incorrect time stamp setting will cause the particles to overlap and so cause "explosion". slope game
