Dear Jibiao, 1. You didn't tell us what you want to do and just claimed that QE is wrong for a molecule. 2. You wrote "[...] results from QE 5.1 are completely wrong [...] results from QE 6.1 is also unsatisfying; the 2pz states should not be populated at a deep level below -28 eV? " 3. I to

Dear Prof. Nicola Marzari, Thank you so much for finding time to handle my email. The input of the CO molecule should be okay because in the calculations of projected pdos onto molecular orbitals everything must be kept exactly the same as the CO/Fe(100) adsorption system (scf). Any input chan

Dear Jibiao, It’s an issue of credibility - if your input points to an inability of doing a correct calculation noone is going to bother checking further. I think everyone was already supernice at looking at your input. Nicola Sent from a tiny keyboard... Contact info: http://theossrv1.epfl.c

Dear Pascal Boulet, Thank you very much for your reply. I think that's not the key of the problem. The question is why QE 6.1 produced acceptable pdos for the CO molecule, but QE 5.1 not. Obviously QE 5.1 has a bug in pdos calculations with kpoints. Davide Ceresoli got similar observation. Doe

Dear Jibiao, what Pascal wrote is a first source of problems in your input - in fact the distance between the different CO molecules of the repeated unit cells is quite small with only ~5 A. Furthermore, please correct me someone if I'm wrong, but if you want to use exact exchange (you specify

Hello, I may be wrong but your input file looks strange: you have an isolated molecule (CO) but you specify 6 as a Bravais lattice and a mesh of k-points. I would choose ibrav=0, kpoint=gamma, assume_isolated=… , and a big box to be sure the molecule is isolated. Perhaps you will get better res
