Hi Chris,
Could you give hints about the calculation of neighbors in LIGGGHTS?
I am using the following commands in the programme.
lattice fcc 0.0013
neighbor 0.00125 bin
It is creating
Total # of neighbors = 48418
Ave neighs/atom = 24.209
Neighbor list builds = 27

the neighbor list contains
the neighbor list contains all particle pairs that meet the following condition (for granular systems):
The distance between the particle centers is less than r1+r2+skin
where r1 and r2 are the particle radii and skin is set by the neighbor command, i.e. 0.00125 in your case
The lattice spacing determines how close to each other the particles are initialized
I would recommend visualizing the system so that you can see what is going on
Cheers, Christoph
