[lammps-users] Error with special bonds command

Hi there

I’ve tested silica particle whose broken bonds at surface were treated with hydrogen atoms using CVFF forcefield. After a few steps of NVT simulations, my simulation stopped with following error message. When I visualized the results, hydrogen atoms at the surface atoms blowed up and both temperature and vdW energy were undesirably increased.

Dear Yen,
Could you please minimize your system before running the MD. That might be creating the problem.
