Hi, I would like to do some MD simulations of materials containing AL and Mg. And I want to allow bond breaking. I think reaxFF withing GULP is the choice. But I found there is no Al and Mg potentials. I searched in literature and found Al and Mg potentials have been out there. So I am wondering why these two potentials are not included in reaxFF within GULP in materials studio? Is there any wany I can import these two potentials to GULP? Thanks a lot.
