[lammps-users] Logarithmic absorbing potential

Dear LAMMPS users,
I want to simulate a system with a absorbing potential with this form: Ln®
Is this potential exist in the potential functions in LAMMPS or not.
Thank you very much,

Absorbing what to what? Do you mean the interaction
between 2 atoms or between a wall and an atom. The
former is pair styles in LAMMPS, but that one isn't
defined. You could use pair_style table and tabulate
it yourself. You can look at the fix wall commands to
see what wall potentials are defined.
