[Pw_forum] Charge is wrong error

[Sunetra Das]

Hello everybody
I am getting wrong charge error as given below, in my output file:









* WARNING: integrated charge=     6.02151254, expected=
6.00000000 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Error in routine electrons (1):     charge is
wrong %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
stopping ...*

I have checked the FAQ section of QE website where the solution is given as
to use a gaussian smearing. I am using a gaussian smearing for my metallic
system, still the error.
I am using QE version 5.0.3. Also the error occurs after several iterations.
I am copying my input file contents below:
