/* 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: Fix pour requires atom attributes radius, rmass
The atom style defined does not have these attributes.
E: Fix pour region ID does not exist
Self-explanatory.
E: Must specify a region in fix pour
The region keyword must be specified with this fix.
E: Fix pour region does not support a bounding box
Not all regions represent bounded volumes. You cannot use
such a region with the fix pour command.
E: Fix pour region cannot be dynamic
Only static regions can be used with fix pour.
E: Insertion region extends outside simulation box
Region specified with fix pour command extends outside the global
simulation box.
E: Must use a z-axis cylinder with fix pour
The axis of the cylinder region used with the fix pour command must
be oriented along the z dimension.
E: Must use a block or cylinder region with fix pour
Self-explanatory.
E: Must use a block region with fix pour for 2d simulations
Self-explanatory.
E: No fix gravity defined for fix pour
Cannot add poured particles without gravity to move them.
E: Cannot use fix pour with triclinic box
This feature is not yet supported.
E: Gravity must point in -z to use with fix pour in 3d
Gravity must be pointing "down" in a 3d box, i.e. theta = 180.0.
E: Gravity must point in -y to use with fix pour in 2d
Gravity must be pointing "down" in a 2d box.
E: Gravity changed since fix pour was created
Gravity must be static and not dynamic for use with fix pour.
W: Less insertions than requested
Less atom insertions occurred on this timestep due to the fix pour
command than were scheduled. This is probably because there were too
many overlaps detected.
E: Cannot change timestep with fix pour
This fix pre-computes some values based on the timestep, so it cannot
be changed during a simulation run.
