Dear All,

I pose the question of my last post in another way:

In a DFT+U scheme, I do a vc-relax calculation with an input in which I had set 
the values for starting_ns_eigenvalue().
In a certain case, the last scf on top of BFGS optimization gives reasonable 
results. Sometime ago Dr Iurii Timrov pointed out that the last scf uses the 
self-consistent occupation matrices resulted from last step of BFGS 
optimization.
Now I would like to repeat the last scf manually, what the code automatically 
executes. To this end, I use ibrav=0, and insert the CELL_PARAMETERS as well as 
the ATOMIC_POSITIONS form the "final coordinates" in vc-relax. In addition, for 
the "occupation" I specify occupations='from_input' as stated in the DOC. 
Unfortunately, I get SEGMENTATION FAULT error.
Could anybody please help to manage this issue?

Best regards,

Subject: [QE-users] disordered values for "starting_ns_eigenvalue(m, ispin, 
itype)"


Dear All,

I am using QE-7.1. In a DFT+U calculation, when I specify the values for 
"starting_ns_eigenvelue(m,ispin,itype)" in a certain order, then in the scf 
cycle, after iteration #1, the WARNING !!! appears that warns about 
modification according to specified starting_ns_eigenvalue().
But the order of the modified eigenvalues are not the same as the ones 
specified in the input. Their magnetic quantum numbers "m" are changed.
Is there any bug with this issue?
Any comments is highly appreciated.

Best,
Mahmoud Payami
