/* ERROR/WARNING messages:
E: Delete_atoms command before simulation box is defined
The delete_atoms command cannot be used before a read_data,
read_restart, or create_box command.
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: Cannot use delete_atoms unless atoms have IDs
Your atoms do not have IDs, so the delete_atoms command cannot be
used.
W: Attempting to delete atoms in rigid bodies
UNDOCUMENTED
W: Ignoring 'compress yes' for molecular system
UNDOCUMENTED
E: Could not find delete_atoms group ID
Group ID used in the delete_atoms command does not exist.
E: Could not find delete_atoms region ID
Region ID used in the delete_atoms command does not exist.
E: Delete_atoms requires a pair style be defined
This is because atom deletion within a cutoff uses a pairwise
neighbor list.
E: Delete_atoms cutoff > max neighbor cutoff
Can only delete atoms in atom pairs that will be in neighbor list.
W: Delete_atoms cutoff > minimum neighbor cutoff
This means atom pairs for some atom types may not be in the neighbor
list and thus an atom in that pair cannot be deleted.
E: Cannot delete_atoms bond yes for non-molecular systems
Self-explanatory.
E: Cannot use delete_atoms bond yes with atom_style template
This is because the bonds for that atom style are hardwired in the
molecule template.
E: Delete_atoms mol yes requires atom attribute molecule
Cannot use this option with a non-molecular system.
