[Wien] Piezoelectric properties

[Oleg Rubel]

Dear Wien2k users and developers,

I am curious whether it is possible to extract piezoelectric properties (e.g., derivative of polarization with respect to strain) using Wien2k? It seems that there is no such a functionality documented in the UG, but maybe there some indirect ways. Ideally, it would be great to reproduce results of Saghi-Szabo et al. [PRL 80, 4321 (1998)] obtained using Berry's phase approach.

Thank you in advance
Oleg
