< p > This command closes the current LAMMPS log file, opens a new file with
2006-09-22 00:22:34 +08:00
the specified name, and begins logging information to it. If the
2015-07-30 22:53:28 +08:00
specified file name is < em > none< / em > , then no new log file is opened. If the
optional keyword < em > append< / em > is specified, then output will be appended
to an existing log file, instead of overwriting it.< / p >
< p > If multiple processor partitions are being used, the file name should
2006-09-22 00:22:34 +08:00
be a variable, so that different processors do not attempt to write to
2015-07-30 22:53:28 +08:00
the same log file.< / p >
< p > The file “ log.lammps” is the default log file for a LAMMPS run. The
