[QE-users] Hubbard U correction for Sn atom error

[Уранбайгал Энхтөр]

Hello!
 I am trying to calculate Li3.9Sn0.1Ti4O12 structure with Hubbard U correction for Ti and Sn atoms inserted in the input file. But as soon as the calculation starts, it stops and turns out error message and the CRASH file says " from set_hubbard_l : error #1 pseudopotential not yet inserted" . On this one youtube video, the person resolves this issue by adding the atom's symbol in the corresponding CASE next to the atoms with the same Hubbard U parameter in the set_hubbard_n.f90 file . Can I use this method to insert the U parameter of Tin (Sn) atom? video link: https://www.youtube.com/watch?v=o9gKn9C35Bo
p.s according to this paper<https://pubs.rsc.org/en/content/articlehtml/2017/ra/c7ra00682a>, Tin atom's band structure is in good agreement with the experimental values when the U parameter is equal to 4 eV for Sn.
Sincerely,
Baigal
