reax and ffield.reax.lg

Hi ,

I am a Lammps user from China, I have two questions want to consult you.One, are there the information of the silicon-oxygen in ffield.reax in the version which have released before LAMMPS 12 ? Two, you added the information of the silicon-oxygen in the ffield.reax.lg in the version LAMMPS 12, can we use these parameters to get amorphous silica? Are these parameters universal? Can you give me some advice?
Best regards,
Liu qingsong

Don't know what LAMMPS 10 vs 12 is. LAMMPS versions have a date.
The pair ReaxFF doc page in LAMMPS gives a WWW site for Adri van Duins
group where you can ask them about what materials ReaxFF has been
parameterized for. We don't release lots of that in LAMMPS, b/c you
can get the parameter files elsewhere and just use them with LAMMPS.
