Dear Matthieu,

thanks for the answer!
It seems to be that I could manage it, since I have the wavefunction files.

Best wishes,
Katalin

I sympathize...

the restart is the same as for GS calculations.

If you have a wavefunction file (_1WF#) you can restart by giving it the proper name and adding irdwf 1 to your input. You can always limit the number of scf steps, and restart in this way. If you use mkmem 0 on a single processor you can usually use one of the temporary scratch files as input. In parallel this doesn't work.

If you have a density and are desperate enough, you can run the phonon calculation with iscf = -2 or -3 to get the wavefunction file mentioned above, then restart your actual calculation.

Otherwise, you're done for...
