/* 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 thermal/conductivity swap value must be positive
Self-explanatory.
W: Fix thermal/conductivity comes before fix ave/spatial
The order of these 2 fixes in your input script is such that fix
thermal/conductivity comes first. If you are using fix ave/spatial to
measure the temperature profile induced by fix viscosity, then this
may cause a glitch in the profile since you are averaging immediately
after swaps have occurred. Flipping the order of the 2 fixes
typically helps.
