Dear users,<div> I want to do phonon calculation for
some structures, but after geometry optimization when I am using
optimized geometry parameters for scf calculation there is difference
in stress of scf calculation and vc-relax calculation which is changing
phonon dispersion. Can anybody please tell me if there is any option to
use the data of relax or vc-relax calculation for phonon dispersion..
Or can I doing phonon calculation along with relax or vc-relax
calculation.?</div>
