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

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

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

Hello everybody<br>
<br>
Sorry for reopening this post, but Im currently struggling to work <br>
with this virtual.x tool.<br>
<br>
I?m working with QE v.6.3, and tried to do the task with both the <br>
updated and original version of virtual.x. After inputting the PP to <br>
mix together, the program generates the output file, but ends with <br>
the message:<br>
<br>
At line 215 of file write_upf_v2.f90<br>
<br>
Fortran runtime error: End of file<br>
<br>
Also, when I open the output PP, NewPseudo.UPF, it contains the <br>
following text:<br>
<br>
<?xml version ?1.0? encoding=?UTF-8??><br>
<br>
<UPF version=?2.0.1?><br>

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.<br>
<br>
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:<br>
<a href="https://www.mail-archive.com/users@lists.quantum-espresso.org/msg33969.html">https://www.mail-archive.com/users@lists.quantum-espresso.org/msg33969.html</a><br>
<br>
The outcome is always the same: the program ends with this fortran runtime error, and the output file comes with two lines of text:<br>
<?xml version="1.0" encoding="UTF-8"?><br>
<UPF version="2.0.1"><br>
<br>
I already tried to reinstall the whole QE, but nothing has changed.<br>

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

or better? you can download directly the? development version from <br>

<br>
The outcome is always the same: the program ends with this fortran <br>
runtime error, and the output file comes with two lines of text:<br>
<?xml version="1.0" encoding="UTF-8"?><br>
<UPF version="2.0.1"><br>
<br>
I already tried to reinstall the whole QE, but nothing has changed.<br>

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

The problem is the<br>

Thanks for the quick reply<br>
<br>
To perform this task, I downloaded the full table of PP?from pseudo <br>
dojo, with the following settings:<br>
<br>
Type:NC SR (ONCVPSP v0.4)<br>
XC: PBE<br>
Accuracy: standard<br>
Format: upf<br>
<br>
My attempts so far were to mix B-C and Si-Al, both unsuccessful. <br>
Maybe my mistake is in the choice of these PP files, and if so, where <br>
can I get the adequate ones to work with the virtual.x?<br>
<br>
Thank you all for the assistance<br>

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

Hello everybody<br>
<br>
Sorry for reopening this post, but Im currently struggling to work <br>
with this virtual.x tool.<br>
<br>
I?m working with QE v.6.3, and tried to do the task with both the <br>
updated and original version of virtual.x. After inputting the PP to <br>
mix together, the program generates the output file, but ends with <br>
the message:<br>
<br>
At line 215 of file write_upf_v2.f90<br>
<br>
Fortran runtime error: End of file<br>
<br>
Also, when I open the output PP, NewPseudo.UPF, it contains the <br>
following text:<br>
<br>
<?xml version ?1.0? encoding=?UTF-8??><br>
<br>
<UPF version=?2.0.1?><br>
<br>
Thank you all for any assistance<br>

<br>
This is normal: if the positions of the atoms are all fixed by symmetry <br>
the Fermi shift is zero.<br>
<br>
Regarding the convergence, it is not converging but it is not exploding <br>
either, which may indicate that it is just a question of reducing the <br>
alpha_mix of phonon to have it converge, by default it is<br>
alpha_mix(1) = 0.7<br>
<br>
You can try<br>
alpha_mix(1) = 0.3<br>
alpha_mix(2) = 0.1<br>
