Dear Paul, commenting your note, and as a chemist, I've been confused by the convenction used in quantum espresso. I'm using a, b, c, alpha, beta and gamma, but not always I've been able to directly translate the content of cif files into QE input... Here is an example about monoclinic input: http:

It may be possible to make QM/MM with QE and some empirical MD package. Some years ago a sort of plugin was build for DLPOLY/Siesta: J. Torras et al., PUPIL: a systematic approach to software integration in multi-scale simulations Comp. Phys. Commun. 177, 265 (2007). Maybe, with a limited amount

Dear sakthi kumaran, It's not possible to perform classical molecular dynamics in Quantum Espresso now. QE can do ab-initio molecular dynamics: Car-Parrinello Molecular Dynamics and Born-Oppenheimer Molecular Dynamics. PS. Next time please take a few seconds to sign your post with your affiliat
