Dear Yun-Peng,Plz try to decrease mixing and perform some convergence tests for your cutoff energy to remove the oscillation of the energy! In addition, this oscillation could also be caused by the unreasonable smearing methods for metals.BestsFang

Thank you for your suggestion, I will first try a smaller beta.

Dear Yun-Peng,
Generally non-collinear calculation is hardest to converge, but I can't
figure it out without knowing your physical system nor without a
complete scf file.
But firstly, you should reduce your mixing factor instead of increase
it , start with mixing_beta = 0.1 and compare.
Dear Peter (or Yun-Peng??),
Two wild guesses: 1) Did you check that the cut-off energies employed
are sufficient? 2) The 'mixing_beta' is very large; the smaller this
value, the tighter the convergence. Well, up to some limit; I would try a
value closer to 0.3 or so. (If your system has a b

According the the error message "reading projwfc namelist", I think the
error comes from the format of your input file, are you sure it is OK to
include blank lines in your input file?

Dear researchers
I have been working on bilayer TMDC materials. I have been facing problems
with projwfc package.
Although, for monolayer 2D materials, I was able to extract PDOS and the
simulation worked fine , whenever I tried a bilayer structure, the projwfc
would give the following error:

Dear Dr. Filipe,
Thank you for your kind assistance! It seems that I cannot get empirical
parameters here, thus performing many tests for k grid convergence as you
said could be the only way to settle the matter.

The numbers indicate, for each band, the number of the representation of
the small group of K. The character table for the point group is written
in the output of the bands.x program and the number corresponds to the

Dear users,
I need parity wave of each bands of band structure (in some specific K
points known as TRIM points) [PRB 76, 045302] to determine the
topological-->trivial phase transition.
In 2013 some body ask about the parity and Prof. Giannozzi suggest to use
bands.x. I did and get a .rap file. B
