On the use of COMB potential for omrfnoy silicon dioxide

Dear creators of the program LAMMPS!
I tried to apply the COMB potential to the calculation of amorphous silica. But the program gives an error when implementing the procedure for balancing charges.
The program manual indicates the possibility of such a calculation. For the case of HfO2, the calculation is carried out!
Can you answer, please, whether it is possible to realize in the program the calculation for amorphous silica. If it is possible, then what is the peculiarity of such a calculation and what is the possible cause of such a mistake?

With best wishes and regards!

       Dear creators of the program LAMMPS!

balancing charges.

​this kind of report is useless without mentioning which LAMMPS version you
are using and on which platform you are running and most importantly what
exactly the error message is. without knowing what the specific error is,
nobody can give advice​ how to eliminate its cause.

    The program manual indicates the possibility of such a calculation.
For the case of HfO2, the calculation is carried out!
   Can you answer, please, whether it is possible to realize in the
program the calculation for amorphous silica. If it is possible, then what
is the peculiarity of such a calculation and what is the possible cause of
such a mistake?

​what kind of systems can or cannot be done with ​COMB is published in the
relevant publications. LAMMPS itself is agnostic towards whether a
simulation is meaningful. all it cares about, whether your input is spelled
orthographically and syntactically correct. beyond that, it is all up to
you and the parameters and settings you enter.
