The codes Quantum Espresso (QE) and Vienna Ab initio Simulation Package (VASP) both use plane wave basis sets and psuedopotentials. Most of the codes in both implementation of DFT uses Fortran code. Do they use similar self-consistent-field procedure to find the solutions of Kohn-Sham equations?

    $\begingroup$ There is a proposal for a Materials Modeling SE which is currently in the commitment phase. Questions like these have been proposed as example questions in its definition phase. You may support the proposal by committing to it. $\endgroup$ – rashid Feb 8 '20 at 11:29

    $\begingroup$ I agree with @rashid, this is exactly the type of question we'd welcome at Materials Modeling, because it's specific to VASP and QE (you might have noticed that most questions on the Computational Science SE are about numerical techniques, which are general to all fields, not specific to Materials). We'd love to have you participate in our Private Beta @phenomenon! But to do that you have to first sign into Area 51 and then click "commit". $\endgroup$ – user1271772 Feb 15 '20 at 3:41
