Bader charge on each atom is different

Post by nulakani »

Dear sir and Bader users

Iam using the VASP4.6.34 and Bader (Version 0.28a 07/12/12) and I followed the following instructions to calculate the bader charge on each atom

1. LAECHG = .TRUE.
2. chgsum.pl AECCAR0 AECCAR2
3. bader CHGCAR -ref CHGCAR_sum
at the end, the valence electrons are exactly converged,but my problem is....the atoms with same neighbours does not contains the same charge.So I increased the FFT grid from 108x108x196 to 216x216x392 still results the same problem.I also tried 324x324x588,but in this case the VASP generates very large CHGCAR AECCAR*(2GB) files and i cannot intigrate them on windows version. plz help me to solve this case.Here the atoms 1-16,17-32,33-40, are Carbons with the respective same environment and 41-48 are Nitrogens. The problem is with 17-32 and 33-40 atoms.Thanks in Advance.

108x108x196
