Cutoff for tensile simulation

Please reply-all to the LAMMPS mailing list.

If you intend to change the cutoffs, you need to completely refit the potential. It is not a trivial task for REBO or AIREBO potentials.


Can you please suggest me how to do refit potential.

I am not aware of refit. I am new to MD.

You need to look at REBO or AIREBO papers that talk about fitting a potential. A mailing list is not the place for that.
