Greetings Experts,
I wish to simulate my system of heavy metal ions like Fe+3 adsorbed on a Si
slab. I usually use revPBE for adsorption simulations. I had an idea of
generating the required pseudopotential with the electronic configuration
of Fe+3 and keeping other parameters the same as Fe. Can
Also with ibrav=0 for a centred cubic structure, I used 2 atoms (0 0 0) and
(0.5 0.5 0.5). On the other hand, with ibrav=3 for cc structure I use a single
atom (0 0 0) and I saw my structure on xcrysden ... its well built so I didn't
understand why with ibrav=0 the filling of d shell is bad.
Looks clear to me. GGA+U is sometimes hard to converge, non collinear
calculations are notoriously hard to converge, hard + hard = very hard

Please plot them with the same x and y ranges and dimensions.

Thank you for your answer. No they are not the same, you fint here in
attachement that when i use ibrav=0 and I define the cell parameter for sur, I
find this fillings with this same range of x.
Thank you

Thanks for the reply.
yes it is converged without taking SOC. But, when i am trying to switch on
the SOC it shows: convergence not
achieved after iterations.

Dear Soumyakanda,
from a very quick look at your input it seems fine to me. Does it crash
after some iterations or right at the start?
do you get convergence if you switch off the U or the SOC?
Good luck,
Matteo

They look pretty much the same to me, except being plot with a different range
along x

I try to calculate the density of state of Nb which is stable in centered
cubic. To do this I use ibrav = 0 and identify the cell_parameter. but with
ibrav = 0 I get a number of electrons from the shell d = 7 electrons (instead
of 10).
I tried to do this with ibrav = 3 which is good for the
Hi users,
I am trying to calculate the band structure and density of states by using
GGA+U+SOC for the sriro3 compound.
however
i
am getting
an error message like : Internal error, convergence has not been achieved.
Is GGA+U+SOC implemented on Quantum espresso ?
here i am attaching my input file
