# (commands for 1st simulation) clear # (commands for 2nd simulation)
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 (shell command), log file status (log command), echo status (echo command), and input script variables except for atomfile style variables (variable command).
