Re: FFT grid resolution convergence problem
The problem with diamond seems to be less severe than that with graphite since the charge assigned to a carbon atom in diamond is not oscilating. But the common problem in both systems (diamond and graphite) is, the charge of each carbon atom should be the same. I think the problem may be related to ...

FFT grid resolution convergence problem
I tested convergence of the Bader charge analysis with respect to the FFT grid resolution. The model I used is bulk diamond, 2 atoms each unit cell. PAW; GGA; KPOINTS 8x8x8. The default NG(X,Y,Z)F is 28. I included core electrons as suggested.
