Dear All,
I have been unable to obtain a Bader charge calculation convergence for one of my systems consisting of a single-layer MoS2 on a sapphire substrate, following the PAW calculations by adding the LAECHG=.TRUE. approach.
Of all the structures that I have simulated for this project, only this system structure is not giving me the electronic convergence (please refer to the "stdout" file attached).
INCAR:
System = MoS2 on Al2O3(0001)
NWRITE = 2
ISTART = 0
ICHARG = 2
INIWAV = 1
ENCUT = 400.0
PREC = ACCURATE
ISPIN = 2
NELMDL = -100
NELM = 1000
EDIFF = 1E-05
LREAL = AUTO
IALGO = 48
LCHARG = .TRUE.
LWAVE = .TRUE.
LVDW = .TRUE.
LAECHG = .TRUE.
ADDGRID = .FALSE.
NSW = 0
NELMIN = 1
IBRION = 2
EDIFFG = -0.013
ISIF = 1
ISYM = 0
POTIM = 0.10
ISMEAR = -5 (-1-Fermi, 1-Methfessel/Paxton)
SIGMA = 0.05 broadening in eV
NPAR = 4
LPLANE = .TRUE.
NCORE = 24
Additionally, I have tried the following steps, to no avail:
i) Increasing the NELM value from 120 up to 1400 (some of my structures did not converge successfully using NELM=120, but did eventually converge when NELM was increased to 400)
ii) Using the Davidson algorithm (IALGO=38), instead of RMM-DIIS (IALGO=48)
iii) increasing the NELMDL steps (from NELMDL= -10 to NELMDL= -100)
iv) using ADDGRID=TRUE
v Re-optimizing the structure using higher EDIFF, EDIFFG, and ENCUT
vi) Using VASP 5.2.12 and VASP 5.3
I would really appreciate any help if you could guide me in the right direction.

Dear Graeme,
Thank you for the quick response.

Re: Bader calculation not converging for a geometry optimized structure
You will have to be more specific about the problem. I ran
chgsum.pl AECCAR0 AECCAR2
to obtain a CHGCAR_sum file. Then I ran the following and you can see the output

Re: Bader calculation not converging for a geometry optimized structure
Dear Graeme,
My apologies for the confusion. I will try to be as specific as possible, while keeping this short.
Usually, the electronic convergences during a Bader calculation would terminate well below the number of NELM steps assigned in the INCAR.
However, for this particular structure, it would not converge (despite producing the CHGCAR file), no matter how large of a NELM value that I assigned to the Bader calculation.
To be more clear, I have attached the stdout file of three separate Bader calculations for comparison.
https://drive.google.com/folderview?id= ... sp=sharing
I want to show that the Bader calculations would keep running until reaching the last NELM step for the same structure, using similar INCAR parameters.
The resulting CHGCAR that is produced after the final NELM step, however, is not to be trusted. I find that their charge values (adsorbate and substrate) are significantly varied.
Notwithstanding the existing situation, I have added an extra sublayer of oxygen atoms at the bottom of the substrate, as shown in the stdout and POSCAR files (see link below).
https://drive.google.com/file/d/0B7ym8d ... sp=sharing
I then performed a standard geometry optimization, before running a Bader calculation; the Bader calculation converged at the NELM step no. 61.
Additionally, I had the same issue with graphene on Al2O3(0001).
I have attached a couple of examples (NELM=120 vs NELM=1600) for reference.
https://drive.google.com/folderview?id= ... sp=sharing
The Bader calculation did not converge in the NELM=120 setup, but did converge at step no.187 in the NELM=1600 setup.
Please let me know if there is something that I missed elaborating?
Thank you in advance.

Re: Bader calculation not converging for a geometry optimized structure
I don't see how convergence of the electronic structure in vasp has anything to do with the Bader calculations. There can certainly be such convergence problems and they are typically solved by changing the electronic structure optimizer or initial conditions (e.g. spin states). Again, I don't see how this is related to the Bader analysis.
