thanks for the replay. I verified and in QE 7.0 the error is printed correctly and the calculation stops. This is not the case for the 6.4.1 version (just a warning for the other users).<br>
<br>
Best regards,<br>

<br>
no, for two reasons:<br>
- your scf calculation was not done with DFT-D3, and<br>
- it is not implemented anyway.<br>
<br>
Demostration:<br>
<br>
$ grep -A1 dftd3 qe-6.4/PHonon/PH/*f90<br>
[...]<br>
qe-6.4/PHonon/PH/phq_readin.f90: IF (ldftd3) CALL errore('phq_readin',&<br>
