ERROR: should be no new maxima in edge refinement

[jisoo93]

Hi, I'm a beginner at bader charge analysis.
I tried to use this for the first time and when I type './bader CHGCAR -ref CHGCAR_sum'
I got a lot of 'ERROR: should be no new maxima in edge refinement' this error message.
how can I solve it please give me some help...
I also attach the files that I used
Thank you.

[njs11@clustermaster 20d]$ ./bader CHGCAR -ref CHGCAR_sum

This often indicates a problem with the charge density file. If you attach it, I can try to see what's going wrong.

[jisoo93]

I thought I attached the file but there wasn't
anyway here's the files
thank you so much

[graeme]

The CHGCAR looks ok but the CHGCAR_sum is not physical -- something is wrong with how it was generated. See the isosurface:

[jisoo93]

thank you so much
I will have a look the cHGCAR_sum
so do I have to fix the code that make CHGCAR_sum?

[graeme]

I would take a look at the files generated by your DFT code. They must be reasonable for the analysis to work properly.

I have seen this topic pop up a few times now.
(Since I have been looking at this site as I have the same error.)
Indeed, I can see very large neg values in my AECCAR0 file.
Still, I used a standard VASP INCAR performing a SCF w LAECHG =.TRUE. (and doubling my initial
values of NGX, NGY, NGZ, from 126-->252)
I am doing spin polarized calcs, but that shouldn't have any effect, with a 2 dim material with a large vacuum.
Perhaps rapid oscillations in the core wave functions for my PAW_PBE psps is the cause of the problem?
(Mo_sv being recommended for Mo).

I can't see anyway to overcome this.
And I think my calcs are good as I generate elec and phys structure very similar to that seen in the literature.

Any ideas?
tnx,
jb

[graeme]

this might be an appropriate question for the vasp guys.

I am also getting the same problem. But when I tried with "-vac off" flag, it gone well and I am getting vacuum charge zero (0). Is there any effect of vacuum charge on the final charge transfer quantity, in case of adsorbed system?
Thanks.

[graeme]

Any changes due to having a vacuum region should be minor. You can easily verify this.

[juganta]

Thanks a lot Professor. What I have mentioned regarding "-vac off", is it a standard procedure? Because you have mentioned that something wrong with CHGCAR_sum file, if this error pop up "ERROR: should be no new maxima in edge refinement" .
For my case I got:
VACUUM CHARGE: 0.5448
VACUUM VOLUME: 684.9021
NUMBER OF ELECTRONS: 1408.0000
Is it too much vacuum charge?
Would you comment on this situation? Thanks a lot!

[juganta]

Here is the ACF.dat.

[graeme]

I would need to see the charge density files to understand the error. But first, take a look at them in a visualizing program -- many of the problems that people report are related to unphysical charge density files.

[juganta]

I have tried to upload files but it failed. Would you please tell me what is the max size of the uploaded files? Thanks

[graeme]

Make sure they are compressed, and attach them separately. I'll check the limit ... Ok, I think it should be 2GB/file now.

You can also use a dropbox link, or any cloud based storage.
