LAMMPS Documentation #################### |version| version ***************** :doc:`What is a LAMMPS version? ` LAMMPS stands for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS is a classical molecular dynamics simulation code with a focus on materials modeling. It was designed to run efficiently on parallel computers. It was developed originally at Sandia National Laboratories, a US Department of Energy facility. The majority of funding for LAMMPS has come from the US Department of Energy (DOE). LAMMPS is an open-source code, distributed freely under the terms of the GNU Public License (GPL). The `LAMMPS website `_ has a variety of information about the code. It includes links to an on-line version of this manual, a `mailing list `_ where users can post questions, and a `GitHub site `_ where all LAMMPS development is coordinated. ---------- The content for this manual is part of the LAMMPS distribution. You can build a local copy of the Manual as HTML pages or a PDF file, by following the steps on the :doc:`Manual build ` doc page. There is also a `Developer.pdf `_ document which gives a brief description of the basic code structure of LAMMPS. ---------- Once you are familiar with LAMMPS, you may want to bookmark :doc:`this page ` since it gives quick access to a doc page for every LAMMPS command. .. _lws: https://lammps.sandia.gov .. _user_documentation: .. toctree:: :maxdepth: 2 :numbered: 3 :caption: User Documentation :name: userdoc :includehidden: Intro Install Build Run_head Commands Packages Speed Howto Examples Tools Modify Python_head Errors Manual_build .. toctree:: :caption: Index :name: index :hidden: commands_list fixes computes pairs bonds angles dihedrals impropers fix_modify_atc_commands Indices and tables ================== * :ref:`genindex` * :ref:`search`
