Description
"""""""""""

This command deletes all atoms, restores all settings to their default
values, and frees all memory allocated by LAMMPS.  Once a clear command
has been executed, it is almost as if LAMMPS were starting over, with
only the exceptions noted below.  This command enables multiple jobs to
be run sequentially from one input script.

These settings are not affected by a clear command: the working
directory (:doc:`shell <shell>` command), log file status (:doc:`log
<log>` command), echo status (:doc:`echo <echo>` command), and input
script variables except for *atomfile* style variables (:doc:`variable
<variable>` command).
