In 6.2 compiled with -DSPIN_BALANCED rvv10 seems to work fine with DFT+U but
DF2 with spin_balanced gives stresses that do not converge. The error is not
large but finite:
df2 dft+u
total stress (Ry/bohr**3) (kbar) P= 24.12
total stress (Ry/bohr**3)
Dear Paolo,
thank you very much for your fast reply. Your patch works fine!
Best regards,

Dear Nkosinathi Malaza (please sign always your posts with name and

It is very likely that your calculation crashed because you ran out of
RAM. I can't say more without seeing your input file. In recent QE
versions there is a rough estimate of the memory
Dear Nam,
My understanding is that the trajectory as printed in VASP’s XDATCAR is folded
or wrapped. As you can see in msd.f90,:
write(6,*) 'Name of unwrapped xyz file’
So the input file should be unwrapped. In other words, you have to first unwrap
the coordinates in XDATCAR. Then you can use
Dear all users,
I encountered one problem when doing consistency test of parameters of
phonon frequencies at Gamma point, shown as in the Table below, in which
are the lowest phonon frequencies of Gamma point after applying ASR.

Dear Quantum Espresso users,
Recently I used the latest version of quantum espresso (6.2) to calculate
the phonon dispersion with nonlocal vdW correction by setting the tag
input_dft='vdW-DF'. And I used the splitting mode for the calculation.
However, the calculation of 'start_q=1, last_q=1' in
