[DFTB-Plus-User] Cell Parameters Optimization

[Benjamin Hourahine]

Hello Marcelo,

at the moment cell parameter optimisation isn't implemented, but
is on the planned feature list for the code.

Regards

Ben

Hi DFTB+ users,

I'm new on DFTB+ and I'm trying to run some tests on periodic systems,
however I couldn't find any flag for cell parameters optimization and I
could notice that they are don't change in any of my calculations. Is this
feature implemented on DFTB+ or do I have to perform such optimization by
manually varying those parameters in order to minimize, for instance the c/a
ratio for hexagonal cells?

Thank you in advance,

Marcelo Zimmer
