[lammps-users] Error: Lost atoms

I just took a look to others mailing list archives and I understarnd that this error has a relationship with bad boundaries, bad geometry or bad time step… I tried to change my box boundaries and the simulation didn’t run… I just attach my input file and my data file that I use to my simulation…

What does "didn't run" mean?
