Hi,
Do first a geometry optimization with a functional that is appropriate for that (PBE, PBEsol?, SCAN, ...). Then, do the mBJ calculation at the optimized geometry. ________________________________ From: Wien <wien-boun...@zeus.theochem.tuwien.ac.at> on behalf of fatima DFT <fatimad...@gmail.com> Sent: Saturday, December 26, 2020 4:55 AM To: A Mailing list for WIEN2k users Subject: Re: [Wien] does dftd3 not work with mBJ Thank you Sir for a detailed explanation. First goal is to optimize the geometry and then band gap. I got your point. Thank you very much Fatima On Sat, Dec 26, 2020, 00:56 Tran, Fabien <fabien.t...@tuwien.ac.at<mailto:fabien.t...@tuwien.ac.at>> wrote: Hello, When mBJ is specified with XC_MBJ in case.in0, ?the total energy is calculated with LDA (grep for :POT in case.scf). There exist no dftd3 parameters for LDA. You have to specify another functional (e.g., PBE) for the energy in case.in0: EX_PBE EC_PBE VX_MBJ VC_LDA Besides, I see no interest in combining dftd3 and mBJ. mBJ is for the band gap, while dftd3 is for the geometry and cohesive energy. What is your goal?

Could someone please confirm that dftd3 does not support mBJ? I can run it with PBE but with mBJ it does not work.
