PME and net charge in the system

Dear all,

How NAMD manages a net charge in the system? i.e. A very big system with
many charged elements where positive and negative charges are
unbalanced, let's say total charge +3 or -4. My idea was that PME do not
converge, But it seems that NAMD does not complain. May you tell me if
some different approximations are used to handle these events?

Regards
Salvatore
