[lammps-users] Screened harmonic potential

LAMMPS LAMMPS Mailing List Mirror

Hi,

I am a beginner with LAMMPS. I have checked the potentials but I couldn’t find my answer. Is there any three-body potential like:

U(θjik) =k2(θjik−θ0)2exp[−(rij/ρ1+rik/ρ2)

This is called screened harmonic in DL-POLY but is there anything sanme in LAMMPS?

Best,
Rose

If it is not listed among the potentials in the LAMMPS manual, it is not available. No style or other user visible feature gets added to LAMMPS without accompanying documentation.
