I'm trying to set up a volume of particles, then move the particle with ID 1 to a position above the volume, change it's diameter and density, and let it drop. Problem is it disappears.
I make the volume separately (create.txt), and then in the main file that (drop.txt) that file is read in and I use the following:
set atom 1 x 0 y 0 z 0 vx 0 vy 0 vz 0
set atom 1 diameter 0.03
set atom 1 density 4865
The first dump file (produced before run 10) contains all the particles, the next output after the set atom commands simply doesn't contain particle 1 anymore.
Liggghts 2.3.7, both make fedora and make openmpi produce this problem.
Here are input files with larger particles that should run in a reasonable time.
It looks like it could be a communication issue - in this case, it works fine on my local laptop, and it works fine on the HPC when only requesting 1 node (12 cores), but the moved particle disappears when I request 2 nodes or more (24+cores).
Tested using 2.3.8, compiled as xt5, and fedora.
