Re: [Wien] Band structure using HSE06
Please read the UG, the section about hybrid DFT. You need a special procedure and commands for bandstructure with hybrid-DFT.

Re: [Wien] Problems of Error of charge leakage when calculating the effective U
Essentially the same question was in fact answered about a week ago, see https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg22219.html This error message is a "feature" of the latest versions which was not there when the early calculations for +U were performed. Do "touch .lcore", assuming that you do have valid RMTs (au not Angstroms). N.B., normally we talk of +U in insulators not metals.

[Wien] Problems of Error of charge leakage when calculating the effective U
Dear WIEN2k experts and users, I am a beginner of WIEN2k. The version is WIEN2k_21.1. Now, I am learning to calculate the effective U of Fe in Fe3Al, following the note ??Calculating the effective U in APW methods. NiO?? by Georg K.H. Madsen and Pavel Novak. When runsp the constrained calculation, the following messages and error appeared: LAPW0 END LAPW1 END LAPW1 END LAPW2 END LAPW2 END CORE END CORE END ERROR: NEC01 charge leakage too large Could you please help me to check which part of my modification went wrong. Thank you for your reply in advance. The specific procedures and related files are as follows: 1. The supercell of Fe3Al has been modified the first Fe. Then run x sgroup and copy case.struct_sgroup to case.struct. 2. Modify inst so that the part of the first Fe looks like: Fe Ar 3 3, 2,2.0 P 3, 2,2.0 P 3,-3,2.5 P 3,-3,0.0 P 4,-1,1.0 N 4,-1,0.5 N Then run the following commands: x lstart x dstart x dstart ?Cup x dstart ?Cdn runsp It's working fine up here. 3. Set two calculations. One with 3.5 (up), 3 (dn). The other with 3.5 (up), 2 (dn). Make the bellowing 4 .inc files.
