Re: [lammps-users] [EXTERNAL] broblem in reax potential

Please send questions to the LAMMPS mailing list.

Regarding your error message, you have entered NUll instead of NULL. However, after you correct this, I suspect you will have additional problems. It is not clear why your are modifying the original script in this way: examples/reaxff/FeOH3/ in.FeOH3
