Hi all,
I have seen the LIGGGHTS v3.x doc about the command 'fix insert/pack'.
For the restriction, it says "The overlapcheck = ‘yes’ option performs an inherently serial operation and will thus not scale well in parallel. For this reason, if you want to generate large systems, you are advised to turn overlapcheck off and let the packing relax afterwards to generate a valid packing.".
What exactly I have to do to let the packing relax afterwards? Thanks.
Regards,
Josh

Limit velocity of particles with large overlaps
You may update the simulation by using fix nve/limit instead of fix nve/sphere for a couple of timesteps. That way you can limit the velocity of the particles and keep the simulation from blowing up in your face.
