Error messages ending in 'Please contact the LAMMPS developers'
---------------------------------------------------------------
Such error messages indicate that something unexpected has happened and
that it will require a good understanding of the details of the design
of LAMMPS to resolve this. This can be due to some bug in contributed
code, and oversight when updating functionality, a feature that is
scheduled to be removed or reaching a combination of flags and settings
that should not be possible or similar.
Even if you find a way to work around this error or warning, you should
contact the LAMMPS developers and prepare a minimal set of inputs that
can be used to reproduce this error or warning. By providing the input,
the LAMMPS developers can then assess whether additional action is
needed and who else to contact about this, if needed.
There are multiple ways to get into contact and report your issue. In
order of preference there are:
- Submit a bug report `issue in the LAMMPS GitHub
<https://github.com/lammps/lammps/issues>` repository
- Post a message in the "LAMMPS Development" forum in the
`MatSci Community Discourse <https://matsci.org/c/lammps/lammps-development/42>`_

The *pad* keyword only applies when a fix produces a file and the output
filename is specified with a wildcard "\*" character which becomes the
timestep. If *pad* is 0, which is the default, the timestep is
converted into a string of unpadded length (e.g., 100 or 12000 or
2000000). When *pad* is specified with *Nchar* :math:`>` 0, the string
is padded with leading zeroes so they are all the same length = *Nchar*\
