Dear Narendra,
While a PBE calculation requires a single FFT for the density the PBE0
calculation requires N_bands*N_bands FFTs for the co-density. In your case
if nspin=1 you would have about 47000 FFTs for a single EXX evaluation.
Despite the number of processors, the number of bands might be

Dear QE experts,
I am trying to refine computation of 3-NT adsorption on metal doped
graphene using QE. This is according to our previous work

With the help of Dr. Guido Fratesi, I am exploring molecularpdos.x to
find the change of HOMO and
Hi all,
I want to generate nmr spectrum for a crystal using quantum
espresso 5.4 version using gipaw. Intially I performed relaxation
calculations for the system and it terminated normally without any errors,
then I performed gipaw calculations using the following input,

Dear All,
I am trying to relax CoMnP unit cell using hubbard_U. But
from output file it is showing Co is d10. So it is in -1 state. Mn is
showing d5 system. So it is in +2 state. But bader charge analysis is
showing Co, Mn and P in 0, +1 and -1 state respectively(showing17.1050
OK, got it... That's why it worked when I chose nr1=nr2=nr3=128 - the
code uses the symmetries including translations in this case as nr1=nr3.
Similarly I should choose at least nk1=nk3, but as the 1st and the 2nd
lattice vectors are nearly the same length I should probably use
nk1=nk2=nk3.
it does not look so much longer than the other to me ...
Anyhow the point is that a grid in order to respect the symmetry must
transform into itself under symmetry operations and yours does not
satisfy this condition for reflexion x -> -x, z -> -z and rotations of
pi around z ...

Dear all
I could not complete my last PBE0 "scf" job containing 434
atoms (CNT+Fullerene). The job could not stop but still running without
writing any more in the output file. These lines are written in the output
34 hours ago .I have tried it twice but I found same thing.
Thanks for the suggestion Stefano!
Yet, lattice vector 3 is in my cell the largest and correspondingly nk3
must be larger than nk1=nk2, or? That's why I choose 10 10 6 (even if I
might have to increase nk3 slightly).
Or do I miss something? I meanwhile also played with the cutoff of the
wave
Dear all,
I am new to quantum espresso with wannier.
I have installed the program and then run all the example. Now I want to
calculate MLWF for FeO for that I have given the input as

Dear all,
I have compiled QE 5.4.0 through gfortran (4.6.2) and gcc (4.6.2) under MinGW
of Windows 7 (32-bit). However, when I run the pw.exe, it gives an error as the
blue information. Even reading the input files successfully run before, the
same error occurred. It seems the program can
