<div>Hi,</div>
<div>The first principle is based on 0K. So, I want to ask if I could calculate sturucture of high temperature. Such as, some structure are znic-blend,but it will transform to wurtzite at high temperature. Could I calculate property of wurtzite of these materials using pwscf ? Such as phonon dispersion, thermal properties.</div>
