# Examples : Pair Potentials

Warning: This is an example potential. Please do NOT use it for any real simulations!

This is a simple pair potential that can be used in potfit. The analytic function used is a Lennard-Jones.

It makes use of the chemical potentials feature. This feature is only available for pair interactions.
