Dear Quantum Espresso Users and Developers,
I have a question regarding a constrained DFT with the PAW/US-PAW. Is it possible to perform calculations in the constrained scheme with QE package. I would like to calculate possible charge transfer in a system.
Regards,

Dear all,
I have tested the image-example for phonon calculations using
QuantumEspresso 6.3. In the case I am using these commands:
mpirun -np 4 pw.x < ...
mpirun -np 4 ph.x -ni 2 < ...
mpirun -np 4 ph.x < ....
everything works fine. However, using this:
mpirun -np 2 pw.x < ...
mpirun -np 4 ph.x -ni 2 < ...
mpirun -np 2 ph.x < ....
yields an error in the last step: "pw.x run with a different number of
processors. Use wf_collect=.true."? However, I have the same number of
processors in pw.x and ph.x and the wf_collect option is activated by
default. So I don't know what is going on.
Best regards,
Malte Sachs

Hi Fabio
Pseudos from pseudo-dojo are perfect, they are norm-conserving and they
are in upf format.
?You have to keep in mind that VCA has sense? for isovalent atoms e. g
C? with Si. Ga.? and In.
Also pseudos would better? be built with the same number of projectors.
Mixing pseudos with a different number of valence electrons like B and
Si is most likely not going to work.
I checked B with Si though,? and disappointingly the program produces an
upf file.? I think that it would be useful at least to print out a very
evident? warning about the usability of such? file.

Hi Fabio
I just tried current version with Al-Ga Ga-In Al-In C-Si Si-Ge P-As,
which are more or less all of pairs which come to my mind where
virtual can be used, and apart from Al-Ga where it doesn't work
because Ga pseudo has usually d semicores every seems to work fine.
Please le me have the 2 pseudos you are trying to mix.

I understood the point of mixing elements with different valence electrons. But even when I try to mix together isoelectronic species (such as Si and C), the generated output file NewPseudo.UPF has no information.
At first I tried to use the virtual.x that comes within QE 6.3, and also tried with this updated version , after making a new virtual.x, based on these instructions:
https://www.mail-archive.com/users@lists.quantum-espresso.org/msg33969.html
The outcome is always the same: the program ends with this fortran runtime error, and the output file comes with two lines of text:
<?xml version="1.0" encoding="UTF-8"?>
<UPF version="2.0.1">
I already tried to reinstall the whole QE, but nothing has changed.

can you try to download the 6.3-backports version from here

or better? you can download directly the? development version from

As you might notice, the second value of Fermi energy shift remains
?0.0000E+00.
This is normal: if the positions of the atoms are all fixed by symmetry
the Fermi shift is zero.
Regarding the convergence, it is not converging but it is not exploding
either, which may indicate that it is just a question of reducing the
alpha_mix of phonon to have it converge, by default it is
alpha_mix(1) = 0.7
You can try
alpha_mix(1) = 0.3
alpha_mix(2) = 0.1
