/* ERROR/WARNING messages:
|
|
|
|
E: Cannot use region INF or EDGE when box does not exist
|
|
|
|
Regions that extend to the box boundaries can only be used after the
|
|
create_box command has been used.
|
|
|
|
E: Illegal ... command
|
|
|
|
Self-explanatory. Check the input script syntax and compare to the
|
|
documentation for the command. You can use -echo screen as a
|
|
command-line option when running LAMMPS to see the offending line.
