Different parameterization of the ReaxFF potential have been
|
|
used in different published works. A small number of these are provided
|
|
in the LAMMPS potentials directory, in the form of ffield.reax.[label]
|
|
files. These can be used with the pair_styles reax and reax/c.
|
|
|
|
For pair_style reax, the command should be as follows:
|
|
|
|
# reax args: hbcut hbnewflag tripflag precision
|
|
pair_style reax 6.0 0 1 1.0e-6
|
|
|
|
except as described below.
|
|
|
|
The mapping from parameter files to publication is as follows:
|
|
|
|
ffield.reax is the same as ffield.reax.mattson
