Dear All,
I would like to confirm calculation results from VASP using QE
(qualitatively, but as quantitatively as possible). To achieve this purpose
I need use pseudo potentials as similar as possible from each other. I do
realize it is not allowed to directly convert VASP pseudo potentials int
Dear all,
I am trying to perform a phonon calculation of Sr2MgWO6 double
perovskite having Fm3m symmetry. I have relaxed the system using the
following input file:

Dear all,
I am a new user in Quantum Espresso.
I am trying to generate the Raman spectra for a polymorph of Indium Oxide
(space group 60, pnma, 20 atoms in unit cell). My input file is as follows:
InO.ph.pnma.in
phonons of InO at Gamma
&inputph
tr2_ph=1.0d-10,
prefix='InO_pnma_opt',
There are many well-known problems of DFT+U, but none that is known to
crash jobs with an obscure message.

1) Remove ESM, check whether you still have problems

I am presently working on Ni-Zn ferrite doped with divalent and trivalent ionsi
did work by synthesizing samples using sol-gel methods and did other
experimental work.now i am interested in giving explanation by doing DFT work.
in this regard i want to how can two or more unit cells be selected (
Hi,
I also have a problem to relax a system of Al and H20, the system does not
finish it crashes. I have attached the output file. Please advise me further
Kind regards

Dear all,
I am trying to have some DFT+U calculations on a system with Tb including f
electrons.
I've never done any Hubbard calc so I was increasing slowly the U parameters.
The calcs goes well up to .8 but when I increase it simply crash after XX
cycles with a nasty mpi error:

Dear All,
I met a problem of convergence in NEB calculation. The calculation ended
in a quite beginning time saying one of the images didn't converged. The input
and output files are attached.
The tail of the output file is follow:

Dear all,
I have recently installed PWscf (version 5.1) on our cluster (4 nodes, 32
cores).
Ifort & mkl version 11.1 has been installed.
When I run pw.x command on every node individually, for both the following
command, it will work properly.
1- /opt/exp_soft/espresso-5.1/bin/pw.x -in scf.in

hi everyone
i need explanation for out put of dos and pdos(projwfc) which are created
by columns.please explain the outfile.thanks in advance.

Dear all,
I want to do phonon calculation on an adsorption system.
I did a test calculation on a system, an molecule is adsorbed on a surface.
I just want to calculate the vibration frequencies of the molecule and
surrounding atom on the surface (19 atom). I set "nat_todo" in the input
