Dear Dr. Giannozzi, Thank you for replying. However, it seems to return exactly the same error message. Would you mind letting me know if there could be some other possible problems? Regards, Yifan On Wed, Dec 1, 2021 at 5:23 AM Paolo Giannozzi wrote: > ("config.guess", not "config.sub") > > O

Hi I had recompiled QE 6.7 and 6.8 with cygwin under Windows ... If I run the result on a test data i get for both the message below short after startup ... Any suggestion what to do ? Related question - does anybody have pre-compiled Windows binary of QE, preferably with SCAN functional suppo

Dear Bhamu, you better use two different kinds for the Fe in octahedral sites: one for 2+ the other for 3+. they are likely to have different U's as well. Matteo Il giorno mer 1 dic 2021 alle ore 11:34 Dr. K. C. Bhamu ha scritto: > Dear Dr. Matteo, > > Thank you very much for the quick respon

Dear Dr. Matteo, Thank you very much for the quick response. Yes, I am doing vc-relax in between each step. Doing vc-relax without adopting geometry information from the previous run. I am only supplying the HP file containing U+V obtained from the previous run for the vc-relax for the next step

Dear Bhamu, > conv_thr = 1.00d-06 In addition to Matteo's comments I would suggest to converge better the ground state. Indeed, something strange is happening at the 4th iteration - a detailed inspection of the output files is needed, but please check what Matteo wrote. HTH Iuri

the fourth iteration does not look too good to me as the U for Fe2 is suddenly going from 4.31 to 0.7. Fe3O4 is a difficult system of its own. are you sure that all the Fe1 are of the same kind (3+)? The system is for sure a mixed valence one but I don't remember how this matches its magnetic struc
