Hi Iurii,
I used ultra soft pps from quantum espresso website. Scalar relativistic for
'vc-relax' - 'relax' and full relativistic 'scf' - 'nscf'.
Problem is solved by removing 'lforcet' tag from nscf input. However It is not
giving "eband, Ef (eV) = ** **" energy output anymore in nscf output file.
Now I added J value too since U+J supports noncollinear calculation. But
vc-relax calculation gives 'forces in the DFT+U+J scheme are not implemented'
error. (Here I'm trying to apply self-consistent procedure for Hubbard and J
parameters)
How can I overcome this problem to compute U and J parameter with hp.x code if
it is possible? (like U and V)

Dear Mustafa,
I do not mange to reproduce your problem.
I have used the latest development version of Quantum ESPRESSO (QE) from Gitlab
(downloaded on 8 February 2023). Also, I changed somewhat your input file to
make it run faster and also I used norm-conserving fully-relativistic
pseudopotentials from the PseudoDojo library (because I do not know which ones
you used). Please try to reproduce my results using the latest development
version of QE. Here are all the files:

If this works, then try once again for your input file using the same
development version of QE. Please note that there are some inaccuracies in the
syntax in your input file, so please pay attention to this and fix it.
HTH

Indeed there seems to be a problem. We will investigate this issue and will
come back to you ASAP.

Dear Mustafa,
> Is it possible to calculate DFT+U with noncollinear?
Yes
Currently, in Quantum ESPRESSO this is implemented in the framework of the
Lichtenstein formulation.
Please provide all the input and output files (using public shared folders,
e.g.Google Drive) that show the problem.

Subject: [QE-users] Zero occupations of Hubbard levels
Hi,
I'm trying DFT+U calculation with spin orbit and noncollinear. However the
current working version is giving the "Hubbard manifold with zero occupations
is not allowed" error.
Then I downloaded the developed version. It is not giving any error anymore but
occupation of hubbard levels are still zero for nscf calculation but not for
scf calculation.
Number of occupied Hubbard levels =3.6094 for last iteration of scf
Number of occupied Hubbard levels =0. for nscf
Is it possible to calculate DFT+U with noncollinear? I mean is this the
problem? or something else. Here I attached scf and nscf inputs and outputs.
Best Regards,
Mustafa.
