/* ERROR/WARNING messages:
|
|
|
|
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.
|
|
|
|
E: Compute group/group group ID does not exist
|
|
|
|
Self-explanatory.
|
|
|
|
E: Compute group/group molecule requires molecule IDs
|
|
|
|
UNDOCUMENTED
|
|
|
|
E: No pair style defined for compute group/group
|
|
|
|
Cannot calculate group interactions without a pair style defined.
|
|
|
|
E: Pair style does not support compute group/group
|
|
|
|
The pair_style does not have a single() function, so it cannot be
|
|
invoked by the compute group/group command.
|
|
|
|
E: No Kspace style defined for compute group/group
|
|
|
|
Self-explanatory.
|
|
|
|
E: Kspace style does not support compute group/group
|
|
|
|
Self-explanatory.
|
|
|
|
W: Both groups in compute group/group have a net charge; the Kspace boundary correction to energy will be non-zero
|
|
|
|
Self-explanatory.
