Hello phonon community,
Thanks to nicola marzari for his advice on the parameters for phonon
calculation.
However, I have tested the convergence of the phonon
frequencies against the wavefunction cutoff, and I do not find convegence.
I am surprised that I obtain very large negative frequencies like
     omega( 1) =      -4.995406 [THz] =    -166.629919 [cm-1]
     omega( 2) =      -4.995406 [THz] =    -166.629919 [cm-1]
     omega( 3) =      -4.474172 [THz] =    -149.243320 [cm-1]
     omega( 4) =      -4.474172 [THz] =    -149.243320 [cm-1]
     omega( 5) =      -2.511886 [THz] =     -83.788069 [cm-1]
     omega( 6) =      -2.511886 [THz] =     -83.788069 [cm-1]
     omega( 7) =       0.734339 [THz] =      24.495069 [cm-1]
     omega( 8) =       1.858145 [THz] =      61.981460 [cm-1]
  etc, up to omega(36)

These frequencies were obtained for a geometry optimized, using the same
parameters in the scf/optimization and phonon calculation. The relevant
parameters are
ecutwfc =60
ecutrho = 320.0
degauss = 0.002
smearing = 'fermi-dirac'
..........
conv_thr =  1.0d-8

for the phonon calculation I have used this input
phonons of Ti3SiC2 at Gamma
 &inputph
  tr2_ph=1.0d-12,
  prefix='tisic',
  epsil=.false.,
  elph=.false.,
  amass(1)=47.8671,
  amass(2)=28.0855,
  amass(3)=12.01078,

  fildyn='/home/gonzalo/eariel/Ti3SiC2/PWSCF/Fonones/Struc_Opt/tisic.dynG',
 /
0.0 0.0 0.0

If I set ecutwfc to 50,40,30, I obtain negative frequencies with much
lower absolute value, near -50 cm^-1, which is normal according to the
forum archives. ecutwfc=60 is certainly larger than
recommended by Nicola, and degauss is much smaller, but I had expected to
find a convergence in the phonon
frequencies, as I have found for the total energies and the forces.

What is the cause of this large negative frequencies and failure of
convergnce. Is it caused by a numerical
instability in the ph code for such a large cutoff?

Are they caused by the small value of degauss? I expected that a very
small 'degauss' caused convergence problem, but not an incorrect result
once
the convergence is achieved. In my case I obtain convergence in 15 scf
iterations and for phonon, in 4 iterations (). Hence I see no problem
here.

My k-point mesh seems converged for the energies. A test with a 15x15x3
mesh preduces a diference in total energy less than 0.00012 Ry, and a
maximum force difference of 0.04eV/Angstrom.

Below, you can see the whole input and output for scf and phonon
calculation.
Thanks
