[lammps-users] error on units box

Hello,

i have a problem:

when i use “units box” in the command (see below), i get an error:

Given the region ID box, I presume you are using the region to define
your simulation
box, in the create_box command. This means that
you are running 2 simulations with different box sizes, which
means the atoms you create could be in totally different
positions. So it's no surprise the 2 simulations behave
differently. You need to decide what geometry you want for
your model and how to populate it correctly.
