I am running a repulsive system at low temperature and high density in 2D. After long enough simulation run, the whole system are moving together towards right-side of x-axis of simulation. I have also set velocity zero all linear and angular.
Kindly assist me here to fix the system moving together along right-side of x-axis of the simulation box.
I have Lammps 10-March 2021 version on ubuntu 20.04 LTS.
