Dear QE users,
I checked entire manual and keywords list of pw.x, there is nowhere
information about manual entering of atomic velocities in the input file,
If necessary sometimes. Moreover, I have seen dynamics_module.f90 file, it
is shown that velocities are initialized from Maxwell-Boltzmann
di
Dear all users,
Can anyone tell me what the least needed parameters to do scf calculations in
quantum espresso are? I would really appreciate it.
Thank you,
Amir

Dear all, I used nq1 = 2, nq2 = 2, nq3 = 2 and nq1 = 4, nq2 = 4, nq3 = 4
,respectively, to do a phonon calculation. There is no imaginary frequency at
the calculated Q points, but after calculations of Q2R and MATDYN, imaginary
frequencies appear near GAMMA point(not GAMMA point).
My setting
Try reducing the tr2_ph parameter. 1D-11 is too high. I have had similar
problems in the past and it was solved by reducing tr2_ph. I would suggest
trying 1D-13 or 1D-14.

Dear QE users,What command line should I use to run pwo2xsf.sh?I tried this but
not success:pwo2xsf.sh --animxsf|-a file.out sc.out

Dear developers,
Thank you for your continues help. I want to know if DFT+U with static
homogeneous finite electric field or Uniaxial tensile strain have been
implemented in any of the QE version. If so, please guide me to any tutorial or
examples links where such calculations have been perform
I tried both but got this error:(standard_in) 1: syntax
error/home/bin/pwo2xsf.sh: line 92: test: -eq: unary operator expected

Currently it is not possible to provide atomic velocities from input in
pw.x. It can be done with the Car-Parrinello code.
Velocities are not used in the Verlet algorithm implemented in pw.x. They
have to be computed from positions as (x(t+dt)-x(t-dt))/(2dt)
