convergence for ESM calculation with on2+EF
Date: 2018/06/21 10:20
Name: jiang

Hi all,

I am trying to calculate Si slab with the ESM model. However, I cannot get convergence. I was wondering if anyone could give me some suggestions?

If I use on4 + EF, the simulation will diverge very early. So I tried to test on2+charge and it still diverge, but at later stages.

I would appreciate if anyone can help me with the on4+EF!

Best,
Jiang

Re: convergence for ESM calculation with on2+EF ( No.1 )

Hi,

I modified the values for the keywords "scf.Kgrid" and "scf.Mixing.Type" in your input file, and a calculation using the modified input file was normally finished.
I think that such a problem can be solved by giving appropriate settings for mixing.

The following is the modified input file:

Re: convergence for ESM calculation with on2+EF ( No.2 )

Hi Yamaguchi san,

Thank you very much! This looks good.
I have another question. I get converged total energy in another simulation, however when I plot the potential in the vhart file, the potential has some oscillation near the ESM region. Is it normal or could this also be removed by adjust settings/mixing?

Best
Jiang

Dear Jiang,

I could reproduce your problem, but I don't know why the nonnegligible oscillation occurs for the vhart file, that is, a term delta VH(r) in the following technical note: http://www.openmx-square.org/tech_notes/tech1-1_2.pdf.

According to a thread below:
http://www.openmx-square.org/forum/patio.cgi?mode=view&no=1587
, you can find a relation between potential terms:
v0=vhart+vna+vxc0,
(you may find the more detailed information in technical notes such as the above).

And, I confirmed there was no oscillation for v0, vna and vxc0, and therefore, due to the oscillation for vhart, the above relation doesn't appear to hold.

The behavior of vhart doesn't seem normal and I don't think this problem may be caused by some wrong values for keywords about SCF.

Regards,
Naoya Yamaguchi
