[Pw_forum] elastic constants

[Stefano Baroni]

As with any other periodic code, I guess: by calculating the stress response to a given strain. If you go through the QE users' manual, I am pretty sure you will find how to instruct QE to calculate the stress tensor (look how to set the variable "tstress"). A HTH
By the way: would you be so kind as to sign future posts to this forum, including your academic affiliation?
Thanks - SB
