[Pw_forum] phonon dos

[bhabya sahoo]

i am calculating vibrational properties using QHA of espresso code
i have the fcc structure having 2 atoms in unit cell
i get the static energy -147.245069 Ry at zero pressure
after that i calculted vibrational properties at zero pressure which is
given below

my question the out put f_vibrational energy is Ry/Cell
so i have to add the f_vibrational energy to the energy at T=0k
so whether i add the f_vibr or i have to divide anything in the vibrational
energy which will be added to cold energy for my system having NaCl
structure
