[lammps-users] Hard core potential

Hi all

Does the LAMMPS have hard core potential? if no, How can do it? I need hard core potential in my simulation.

Thanks a lot

If you mean a potential that is infinite at overlap and 0 otherwise,
then no. All potentials in LAMMPS (and MD codes generally)
are soft. Hard potentials are more generally used in Monte Carlo
models, not MD.
