Hello,

I am trying to calculate phonons at gamma. Ground state calculation has already been done. In the second stage of calculation of d/dk, I get the following message:

symq3 : found symmetry 1 preserves q
symq3 : found symmetry 1 + TimeReversal preserves q
symq3 : able to use time-reversal symmetry.
(except for gamma, not yet able to use time-reversal symmetry)

getcut: wavevector= 0.0000 0.0000 0.0000 ngfft= 108 60 60
ecut(hartree)= 46.000 => boxcut(ratio)= 2.02987

mkrho.F90:531:BUG
the bandfft tabs are not allocated !
Action : contact ABINIT group.

.Delivered 1 WARNINGs and 4 COMMENTs to log file.
-P-0000
-P-0000 leave_new : decision taken to exit ...


My parallelisation parameters are the following:

#Parallelisation parameters
npkpt 108
npspinor 1
npband 3
npfft 1
bandpp 4
paral_kgb 1


Wonder if it is really a BUG or an error on my part.

Thank you,

George

Hello,

1) you need a more descriptive title

2) looks like the fft parallelization is not active for dfpt. You should stick to kpt and band, and for dfpt normally it does it automatically (can someone confirm this?)

cheers
