== Force fields classified by material ==
All supported force fields are listed on the [https://lammps.sandia.gov/doc/Intro_features.html#ff package web site],
classified by functional form (e.g. pairwise potentials, many-body potentials, etc.)
The large number of supported force fields makes LAMMPS suitable for many areas of application.
Here is a list of types of modelling and force fields suitable for each:
