Dear Sir,
As per the instruction Qe phonopy is only supported for ibrav=0 type
crystal structure but for my case it is hexagonal(ibrav=4),can anything be
done here using phonopy?

Thanks and regards,
Anindya Bose

supercell(consisting defects) with 32 processors but it is taking too much
time and the predicted time of computation can be endless.Is there any
other way to do such phonon calculation where all the phonon modes can be
computed parallely so that the computation time will be minimized.The
supercell having 150 phonon modes.Is there any way out.Please help.
