This is the list of standard packages in LAMMPS. The link for each package name gives more details.
Standard packages are supported by the LAMMPS developers and are written in a syntax and style consistent with the rest of LAMMPS. This means the developers will answer questions about them, debug and fix them if necessary, and keep them compatible with future changes to LAMMPS.
The "Example" column is a sub-directory in the examples directory of the distribution which has an input script that uses the package. E.g. "peptide" refers to the examples/peptide directory; USER/atc refers to the examples/USER/atc directory. The "Library" column indicates whether an extra library is needed to build and use the package:
