Dear lammps users,
Hello everybody
I’d like to apply a constant external electric field on my system. I know that the external electric field in my simulations is a classical approximation and it just impose electric forces on my charged elements. For comparison of an external electric field operation between ReaxFF Fortran source code and reax/c lammps package I made a very simple system as below:
200 H2 molecules in a cubic box (a=160 A)

Dear lammps users,

I have a questions, I didn’t have any error on the electric field command,
yet I didn’t see any result. What accrues for the electric field in the
lammps package? Pleas kindly help me on this problem.
please spend some time reading the documentation. the description of the
fix efield command says it all:
Add a force F = qE to each charged atom in the group due to an external
electric field being applied to the system.
so what happens to F when q is zero?
axel.
