This package provides a pair_style kim command which is a wrapper on
the Knowledge Base for Interatomic Models (KIM) repository of
interatomic potentials, so that they can be used by LAMMPS scripts.
This package provides the kim_init, kim_query, kim_interactions, and
the pair_style kim command which are wrappers on the Knowledgebase of
Interatomic Models (KIM) repository of interatomic potentials, so that
they can be used by LAMMPS scripts.
Information about the KIM project can be found at https://openkim.org.
The KIM project is lead by Ellad Tadmor and Ryan Elliott (U Minn) and
James Sethna (Cornell U). Ryan Elliott is the main developer for the
KIM API and he also maintains the code that implements the pair_style
kim command.

Using this package requires the KIM library and its models
Using this package requires the KIM-API library and its models
(interatomic potentials) to be downloaded and installed on your
system. The library can be downloaded and built in lib/kim or
elsewhere on your system, which must be done before bulding LAMMPS
with this package. Details of the download, build, and install
process for KIM are given in the lib/kim/README file, and scripts
are provided to help automate the process. Also see the LAMMPS
manual for general information on building LAMMPS with external
process for the KIM-API are given in the lib/kim/README file, and
scripts are provided to help automate the process. Also see the
LAMMPS manual for general information on building LAMMPS with external
libraries. The settings in the Makefile.lammps file in lib/kim must
be correct for LAMMPS to build correctly with this package installed.
However, the default settings should be correct in most cases and the
Makefile.lammps file usually will not need to be changed.
Once you have successfully built LAMMPS with this package and the KIM
library you can test it using an input file from the examples dir:
library you can test it using an input files in the examples dir:
./lmp_serial -in lammps/examples/kim/in.kim.lj
This pair_style was written by Ryan S. Elliott (U Minn).
These commands were written by Ryan S. Elliott (UMN), Ellad B. Tadmor
(UMN) and Axel Kohlmeyer (Temple U).

E: Species XXX is not supported by this KIM Simulator Model
