The files in this package are a potpourri of (mostly) unrelated features contributed to LAMMPS by users. Each feature is a single pair of files (*.cpp and *.h). More information about each feature can be found by reading its doc page in the LAMMPS doc directory. The doc page which lists all LAMMPS input script commands is as follows: doc/Section_commands.html, subsection 3.5 User-contributed features are listed at the bottom of the fix, compute, pair, etc sections. The list of features and author of each is given below. You should contact the author directly if you have specific questions about the feature or its coding. ------------------------------------------------------------ angle_style cosine/shift, Carsten Svaneborg, science at zqex.dk, 8 Aug 11 angle_style cosine/shift/exp, Carsten Svaneborg, science at zqex.dk, 8 Aug 11 angle_style fourier, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 angle_style fourier/simple, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 angle_style dipole, Mario Orsi, orsimario at gmail.com, 10 Jan 12 angle_style quartic, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 bond_style harmonic/shift, Carsten Svaneborg, science at zqex.dk, 8 Aug 11 bond_style harmonic/shift/cut, Carsten Svaneborg, science at zqex.dk, 8 Aug 11 compute ackland/atom, Gerolf Ziegenhain, gerolf at ziegenhain.com, 4 Oct 2007 compute temp/rotate, Laurent Joly (U Lyon), ljoly.ulyon at gmail.com, 8 Aug 11 dihedral_style cosine/shift/exp, Carsten Svaneborg, science at zqex.dk, 8 Aug 11 dihedral_style fourier, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 dihedral_style nharmonic, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 dihedral_style quadratic, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 dihedral_style table, Andrew Jewett, jewett.aij@gmail.com, 10 Jan 12 fix addtorque, Laurent Joly (U Lyon), ljoly.ulyon at gmail.com, 8 Aug 11 fix imd, Axel Kohlmeyer, akohlmey at gmail.com, 9 Nov 2009 fix smd, Axel Kohlmeyer, akohlmey at gmail.com, 19 May 2008 improper_style cossq, Georgios Vogiatzis, gvog at chemeng.ntua.gr, 25 May 12 improper_style fourier, Loukas Peristeras, loukas.peristeras at scienomics.com, 27 Oct 12 improper_style ring, Georgios Vogiatzis, gvog at chemeng.ntua.gr, 25 May 12 pair_style coul/diel, Axel Kohlmeyer, akohlmey at gmail.com, 1 Dec 11 pair_style dipole/sf, Mario Orsi, orsimario at gmail.com, 8 Aug 11 pair_style edip, Luca Ferraro, luca.ferraro at caspur.it, 15 Sep 11 pair_style eam/cd, Alexander Stukowski, stukowski at mm.tu-darmstadt.de, 7 Nov 09 pair_style gauss/cut, Axel Kohlmeyer, akohlmey at gmail.com, 1 Dec 11 pair_style lj/sf, Laurent Joly (U Lyon), ljoly.ulyon at gmail.com, 8 Aug 11 pair_style meam/spline, Alexander Stukowski (LLNL), alex at stukowski.com, 1 Feb 12 pair_style meam/sw/spline, Robert Rudd (LLNL), robert.rudd at llnl.gov, 1 Oct 12 pair_style tersoff/table, Luca Ferraro, luca.ferraro@caspur.it, 1 Dec 11
