[Pw_forum] about the nelec in the outputfile

[Duy Le]

Did you check carefully? If you change the tot_charge, the number of
electron must be charged accordingly. The starting charge is generated to be
a non-charge system but then will be renormalized accordingly.

That number 200 is the total electron in your unit cell corresponding to the
neutral system.
