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"_lws has a variety of information about the code. It includes links to an on-line version of this manual, a "mail list"_http://lammps.sandia.gov/mail.html where users can post questions, and a "GitHub site"https://github.com/lammps/lammps where all LAMMPS development is coordinated. :line "PDF file"_Manual.pdf of the entire manual, generated by "htmldoc"_http://freecode.com/projects/htmldoc 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 "Manual build"_Manual_build.html doc page. There is also a "Developer.pdf"_Developer.pdf document which gives a brief description of the basic code structure of LAMMPS. :line This manual is organized into the following sections. Once you are familiar with LAMMPS, you may want to bookmark "this page"_Commands.html since it gives quick access to a doc page for every LAMMPS command. <!-- RST .. 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 Indices and tables ================== * :ref:`genindex` * :ref:`search` END_RST --> <!-- HTML_ONLY --> "Introduction"_Intro.html :olb,l "Install LAMMPS"_Install.html :l "Build LAMMPS"_Build.html :l "Run LAMMPS"_Run_head.html :l "Commands"_Commands.html :l "Optional packages"_Packages.html :l "Accelerate performance"_Speed.html :l "How-to discussions"_Howto.html :l "Example scripts"_Examples.html :l "Auxiliary tools"_Tools.html :l "Modify & extend LAMMPS"_Modify.html :l "Use Python with LAMMPS"_Python_head.html :l "Errors"_Errors.html :l "Building the LAMMPS manual"_Manual_build.html :l :ole <!-- END_HTML_ONLY --> </BODY>
