/* 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: Must use dpd/fdt pair_style with fix shardlow
Self-explanatory.
E: Must use pair_style dpd/fdt or dpd/fdt/energy with fix shardlow
E: A deterministic integrator must be specified after fix shardlow in input
file (e.g. fix nve or fix nph).
Self-explanatory.
E: Cannot use constant temperature integration routines with DPD
Self-explanatory. Must use deterministic integrators such as nve or nph
E: Fix shardlow does not yet support triclinic geometries
Self-explanatory.
E: Shardlow algorithm requires sub-domain length > 2*(rcut+skin). Either
reduce the number of processors requested, or change the cutoff/skin
The Shardlow splitting algorithm requires the size of the sub-domain lengths
to be are larger than twice the cutoff+skin. Generally, the domain decomposition
is dependant on the number of processors requested.
