W: Pair dsmc: num_of_collisions > number_of_A

W: Pair dsmc: num_of_collisions > number_of_B

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: Incorrect args for pair coefficients
Self-explanatory. Check the input script or data file.
E: Tried to convert a double to int, but input_double > INT_MAX
Self-explanatory.
