/* 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: Region ID for compute chunk/atom does not exist
Self-explanatory.
E: Compute chunk/atom molecule for non-molecular system
Self-explanatory.
E: Compute chunk/atom without bins cannot use discard mixed
That discard option only applies to the binning styles.
E: Compute chunk/atom sphere z origin must be 0.0 for 2d
Self-explanatory.
E: Compute chunk/atom cylinder axis must be z for 2d
Self-explanatory.
E: Compute ID for compute chunk /atom does not exist
Self-explanatory.
E: Compute chunk/atom compute does not calculate per-atom values
Self-explanatory.
E: Compute chunk/atom compute does not calculate a per-atom vector
Self-explanatory.
E: Compute chunk/atom compute does not calculate a per-atom array
Self-explanatory.
E: Compute chunk/atom compute array is accessed out-of-range
The index for the array is out of bounds.
E: Fix ID for compute chunk/atom does not exist
Self-explanatory.
E: Compute chunk/atom fix does not calculate per-atom values
Self-explanatory.
E: Compute chunk/atom fix does not calculate a per-atom vector
Self-explanatory.
E: Compute chunk/atom fix does not calculate a per-atom array
Self-explanatory.
E: Compute chunk/atom fix array is accessed out-of-range
the index for the array is out of bounds.
E: Variable name for compute chunk/atom does not exist
Self-explanatory.
E: Compute chunk/atom variable is not atom-style variable
Self-explanatory.
E: Compute chunk/atom for triclinic boxes requires units reduced
Self-explanatory.
E: Compute ID for compute chunk/atom does not exist
Self-explanatory.
E: Molecule IDs too large for compute chunk/atom
The IDs must not be larger than can be stored in a 32-bit integer
since chunk IDs are 32-bit integers.
E: Compute chunk/atom ids once but nchunk is not once
You cannot assign chunks IDs to atom permanently if the number of
chunks may change.
E: Two fix ave commands using same compute chunk/atom command in incompatible ways
They are both attempting to "lock" the chunk/atom command so that the
chunk assignments persist for some number of timesteps, but are doing
it in different ways.
E: Fix used in compute chunk/atom not computed at compatible time
The chunk/atom compute cannot query the output of the fix on a timestep
it is needed.
W: One or more chunks do not contain all atoms in molecule
This may not be what you intended.
E: Invalid bin bounds in compute chunk/atom
The lo/hi values are inconsistent.
E: Compute chunk/atom bin/sphere radius is too large for periodic box
Radius cannot be bigger than 1/2 of any periodic dimention.
E: Compute chunk/atom bin/cylinder radius is too large for periodic box
Radius cannot be bigger than 1/2 of a non-axis periodic dimention.
E: Cannot use compute chunk/atom bin z for 2d model
Self-explanatory.
