Hi
I apology to QE users, but my solution: Use instead of QE CASTEP, witch generates pseudopotentials on the fly optimized for given functional (no databases used) ... It solves all the pseudopotential database issues .. Supports rSCAN, r2SCAN ... I hope QE authors will sometime add to the PW the on-the fly pseudopotential generation functionality with no need to have external files ...

Dr Yi-Min Ding reported a similar issue (https://lists.quantum-espresso.org/pipermail/users/2023-March/050277.html) and someone suggested that the issue could be due to the pseudos have been generated with PBE and then used with the SCAN functional. I tested NCPP from PseudoDojo library and SG15 library, both resulted in convergence issues when spin-polarized calculation is enabled. I have include the link for NCPP files from both libraries below, any advice would be appreciated. NCPP for Ni, O and H: PseudoDojo: http://www.pseudo-dojo.org/ SG15: http://quantum-simulation.org/potentials/sg15_oncv/ Thank you, Jing Lian Ng 2nd Year PhD Student at University of Texas _______________________________________________ The Quantum ESPRESSO community stands by the Ukrainian people and expresses its concerns about the devastating effects that the Russian military offensive has on their country and on the free and peaceful scientific, cultural, and economic cooperation amongst peoples _______________________________________________ Quantum ESPRESSO is supported by MaX (www.max-centre.eu) users mailing list users@lists.quantum-espresso.org https://lists.quantum-espresso.org/mailman/listinfo/users
