hi everybody
how MSD show that the system get to equilibrium?
I plot msd vs. time and it become a line with slope and arise by time
, but have a bit fluctuation , Is that mean system get to equilibrium
or it should be linear with zero slope?
my system is ionic liquid
thanks

This is a basic physics question and has nothing to do with LAMMPS.
