LAMMPS Documentation :c,h3 Version info: :h4 The LAMMPS "version" is the date when it was released, such as 1 May 2010. LAMMPS is updated continuously. Whenever we fix a bug or add a feature, we release it immediately, and post a notice on "this page of the WWW site"_bug. Each dated copy of LAMMPS contains all the features and bug-fixes up to and including that version date. The version date is printed to the screen and logfile every time you run LAMMPS. It is also in the file src/version.h and in the LAMMPS directory name created when you unpack a tarball. If you browse the HTML doc pages on the LAMMPS WWW site, they always describe the most current version of LAMMPS. :ulb,l If you browse the HTML doc pages included in your tarball, they describe the version you have. :l The "PDF file"_Manual.pdf on the WWW site or in the tarball is updated about once per month. This is because it is large, and we don't want it to be part of very patch. :ule,l LAMMPS stands for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS is a classical molecular dynamics simulation code designed to run efficiently on parallel computers. It was developed at Sandia National Laboratories, a US Department of Energy facility, with funding from the DOE. It is an open-source code, distributed freely under the terms of the GNU Public License (GPL). The primary developers of LAMMPS are "Steve Plimpton"_sjp, Aidan Thompson, and Paul Crozier who can be contacted at sjplimp,athomps,pscrozi at sandia.gov. The "LAMMPS WWW Site"_lws at http://lammps.sandia.gov has more information about the code and its uses. :link(bug,http://lammps.sandia.gov/bug.html) :link(sjp,http://www.sandia.gov/~sjplimp) :line The LAMMPS documentation is organized into the following sections. If you find errors or omissions in this manual or have suggestions for useful information to add, please send an email to the developers so we can improve the LAMMPS documentation. Once you are familiar with LAMMPS, you may want to bookmark "this page"_Section_commands.html#comm at Section_commands.html#comm since it gives quick access to documentation for all LAMMPS commands.
