Re: [QE-users] DFT relaxation steps

2021-11-30 Thread Giuseppe Mattioli
Dear Sunil Kumar Check the structure first. I opened your file with xcrysden and even if it is not totally weird, it is a bit strange (Ni-Y distances of 2.2 A are likely wrong...). Moreover, are you sure you want to use the LDA (PZ) functional? The electronic structure of a TM oxide will l

[QE-users] convergence issue in DFT_U+V calculation

2021-11-30 Thread Dr. K. C. Bhamu
Dear Iurii, This is from the calculation without nbnd in QE input file (QE input and HP input are supplied at the end of this email). I am trying to get a converged value of U+V. Up to four steps, all the calculations seem to be fine (other than the converged value of U+V). But in the 5th step, I s

[QE-users] DFT convergence problem

2021-11-30 Thread Dr. SUNIL KUMAR
Dear QE developers and Users. We are doing DFT simulation of Monoclinic YNiO3 with and without oxygen vacancy. During the vc-relax and relax relaxation step, energy does not converge and simulation ends with error msg " convergence NOT achieved after 200 iterations: stopping" . I have tried ma

Dear Mahmoud Unfortunately the 6.2.2 version of QE was not tagged ( we were in the transition between svn and git ), but there were no changes in atomic code between 6.2.1 and 6.2.2. Yonu may download that version here ( https://gitlab.com/QEF/q-e/-/releases/qe-6.2.1  ). The use_xsd flag is u
