Dear all,
I am using CH.airebo to simulate the interaction between carbon atoms in a graphene. I found that even I turned off the LJ term in AIREBO, I still got non-zero van der Waals energy E_vdwl. Meanwhile, bond energy, angle energy and dihedral energy are all zero. I am wondering why E_vdwl is not zero and how can I get the bond energy, angle energy and dihedral energy.
Thanks,
Zhao
