hbondchk failed

hello
I use pair_style hybrid to simulate 10 water with a graphene oxide sheet( lammps vision 10 Aug 2015 ). The graphene atoms interact with each other via an reax/c potential, the water atoms interact with each other via a lj/cut potential, and the water/GO interaction is also computed via a lj/cut potential. but when it runs , no matter how i change the timestep ,the safezone or mincap ,hbondchk failed is happened soon or later.

I’d appreciate if you can tell me the reason why errors happen and how to fix them !

The system has bad dynamics (evidented by the large increase in temperature and etotal), which could have arose from bad input structure and force field parameters. The latter being very likely since hybriding ReaxFF with other force fields is not recommended unless very careful work has been done.

hbondchk error occurs when the hydrogen bond neighbor list increased/changed too much in one step - a result of bad dynamics. You can increase the mincap and safezone numbers to very large ones, but that will only fix the sympton. You should carefully examine your snapshot and find which atoms have unusually large energy and fix their force field parameters.
