lammps/src/USER-COLVARS

This package implements the "fix colvars" command which can be used
in a LAMMPS input script.

This fix allows use of "collective variables" to implement Adaptive
Biasing Force, Metadynamics, Steered MD, Umbrella Sampling and
Restraints.

This package uses an external library in lib/colvars which must be
compiled before making LAMMPS.  See the lib/colvars/README file and
the LAMMPS manual for information on building LAMMPS with external
libraries.  The settings in the Makefile.lammps file in that directory
must be correct for LAMMPS to build correctly with this package
installed.

The external library is a portable collective variable module library
written and maintained by Giacomo Fiorin (ICMS, Temple University,
Philadelphia, PA, USA) and Jerome Henin (IBPC, CNRS, Paris, France).

More info about this library can be found at: http://colvars.github.io

and in these publications:

The colvars fix implementes a thin interface layer, which exchanges
information between LAMMPS and the collective variable module.  This
interface was written and is maintained by Axel Kohlmeyer
(akohlmey@gmail.com)

See the doc page of fix colvars for more details.

There is a reference manual for the package included with the LAMMPS
doc pages: doc/PDF/colvars-refman-lammps.pdf

There are example scripts for using this package in
examples/USER/colvars.
