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.
