airebo potential

Hi everyone

Can airebo potential be used in a system where units are in real? what would be the problems?

Best regards,

the answer to your question is in the documentation for the airebo
pair style (under Restrictions):

The CH.airebo potential file provided with LAMMPS (see the potentials
directory) is parameterized for metal units. You can use the AIREBO or
REBO potential with any LAMMPS units, but you would need to create
your own AIREBO potential file with coefficients listed in the
appropriate units if your simulation doesn't use "metal" units.
