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: | |||
* | * Biomolecules: CHARMM, AMBER, OPLS, COMPASS (class 2), long-range Coulombics via PPPM, point dipoles, ... | ||
* | * Polymers: all-atom, united-atom, coarse-grain (bead-spring FENE), bond-breaking, … | ||
* | * Materials: EAM and MEAM for metals, Buckingham, Morse, Yukawa, Stillinger-Weber, Tersoff, EDIP, COMB, SNAP, ... | ||
* | * Reactions: AI-REBO, REBO, ReaxFF, eFF | ||
* | * Mesoscale: granular, DPD, Gay-Berne, colloidal, peri-dynamics, DSMC... | ||
Combinations of potentials can be used for hybrid systems, e.g. water on metal, polymer/semiconductor interfaces, colloids in solution, ... | |||
