Dear lammps user:
i have performed a MD run using ReaxFF potential and reax/c package as implemented in the last version of lammps code.
the input file is the same as in the example directory.
using the in.file the run was finished without any problems. however, when i have changed one or more parameters in the lmp_control file such as : nbrhood_cutoff, hbond_dist_cutoff,angle_info … the run was interompted and the warning message"unknown parameter" appear which appear in contradiction with the manual instruction which indicate that these parameterscan been changed as desired by the user.
i would also ask how to change the nonbonded_intr_dist_cutoff parameters which has a stantard value of 10 A°.
best regards
