Using this package:

  • [Required] This package expects a python 3.6+ version.
  • [Required] Compile LAMMPS (lammps.sandia.gov) as a shared library, detailed instructions can be found here docs/LAMMPS.md. If you can open python and run import lammps; lmp = lammps.lammps() and it succeeds, you should be good.

Installing:

  • Put this directory somewhere that you like.
  • Add this directory in your Python path.
  • See docs/INSTALL.md for more information

Running:

  • python -m fitsnap3 [options] infile
  • Command line options can be seen with python -m fitsnap3 -h
  • Input files are described by docs/TEMPLATE.in and docs/GROUPLIST.template
  • Examples of published SNAP interatomic potentials can be found in examples/

Version Control:

  • stable branch is the latest validated stable version of the code. It is recommended for new users.
  • master branch reflects all of the latest code changes. It is intended for active developers.
