</div>
<div>yes, but typically one does MD in aperiodic systems described by large supercells, so using more k-points than Gamma only is seldom useful

No, it is a little more complex. AFAIK, you can perform <br>
spin-unrestricted fixed-occupation MD simulations (no smearing), or <br>
ensemble-DFT simulations. There are limitations in the latter case <br>
(BOMD only, CG diaginalization, ...), but I cannot provide further <br>
information because I've never used it. Flick through <br>
CPV/examples/example08 for details<br>
