I strongly suggest that you also look at the magnetic moments and what is going on at the Fermi energy and with the 4f. Both :DIS &:ENE are relatively crude tests and often don't tell the whole story.
HDLO can also be important for large RMTs similar to what you have. Last, but not least, did you use runafm? _____ Professor Laurence Marks "Research is to see what everybody else has seen, and to think what nobody else has thought", Albert Szent-Gyorgi www.numis.northwestern.edu On Wed, Oct 31, 2018, 4:10 PM t...@theochem.tuwien.ac.at < t...@theochem.tuwien.ac.at> wrote: > Hi, > > Can you show us how :DIS and :ENE are changing (grep them in case.scf). > > FT > > On Wednesday 2018-10-31 21:35, Kefeng wang wrote: > > >Date: Wed, 31 Oct 2018 21:35:38 > >From: Kefeng wang <wangk...@gmail.com> > >Reply-To: A Mailing list for WIEN2k users < > wien@zeus.theochem.tuwien.ac.at> > >To: wien@zeus.theochem.tuwien.ac.at > >Subject: [Wien] problems with convergence of SCF for AFM HoPtBi > > > >Dear all, > >I am using wien17.1 to perform the DFT calculations for HoPtBi.
