Convergence problem in magnetic slab calculation Date: 2018/01/16 12:55 Name: Eike F. Schwier   <schwier@hiroshima-u.ac.jp> Dear All, I am trying to calculate the surface relaxation of Fe(001) slabs at different tensile and compressive strains. However for the slab I am using convergence is very slow and sometimes fails to reach the scf.criterion. I already tried to play with electronic tmperature, mixing history and start pulay. Does anybody have some idea what other parameters may be adjusted? Can this be a problem of the choice of mixer? Or a wrong kerker factor? Does anybody have some suggestions? best regards, Eike # # Definition of Atomic Species # Species.Number 1 <Definition.of.Atomic.Species Fe Fe6.0S-s3p3d2f1 Fe_CA13S Definition.of.Atomic.Species> # #

Schwier  <schwier@hiroshima-u.ac.jp> Dear Samuel, thanks for the link. I already tried the last two options previously but forgot the VNA / overcompleteness. Maybe it helps. best, Eike Re: Convergence problem in magnetic slab calculation ( No.3 ) Date: 2018/03/03 21:29 Name: T. Ozaki References: t-ozaki@issp.u-tokyo.ac.jp Hi, I also tested your system and found that the system is very difficult to get convergence due to the anisotropic structure that one of unit vector is much longer than the others. I noticed that even careful tuning several parameters of mixing may not help acceleration of the convergence, and that your parameter settings seem to be almost best choice. This may suggest a need for further improvement of mixing method for such an anisotropic systems. Anyway, I was able to manage to get the convergent structure as can be seen at http://t-ozaki.issp.u-tokyo.ac.jp/openmx-files/Fe001.dat http://t-ozaki.issp.u-tokyo.ac.jp/openmx-files/fe001.out Thank for sharing your experience. Regards, TO Re: Convergence problem in magnetic slab calculation ( No.4 ) Date: 2018/04/05 07:32 Name: Eike F Schwier  <schwier@hiroshima-u.ac.jp> Dear Ozaki-sensei, thank you very much for testing my structure. In the meantime I found some indication that the problem of convergence seems to be related to the magnetic structure / spin properties. When I was relaxing a Pb(110) slab I had no problems with convergence (even up to 65 ML), but once I included NC and Spin-Orbit Coupling even restarting a converged "nomd" calculation can take many SCF iterations, while the nonmagnetic slab seems to restart fine. I also found during some recent testing that the EF relaxation seems to converge to a relaxed geometry faster compared to the RF I initially used, but I only tried for thinner Fe slabs so far. best regards, Eike Re: Convergence problem in magnetic slab calculation ( No.5 ) Date: 2018/04/22 22:34 Name: reza  <e_majidinia@yahoo.com> hello .
