Dear nicola,<br><br>thank you suggestion.<br>I'll make the NVE calculation after random the ions.<br><br>I wonder what temperature is demand for the NVE?<br>if the temperature is too high than the demanded temperature, should I make the smaller random again?<br>
For example, if the temperature is ~1000K after NVE, but the demanded is 300K, should I make the random process again using smaller amprp(1~3)?<br><br>thank you <br><br>vega<br><br><div class="gmail_quote">On Fri, Nov 27, 2009 at 10:17 AM, Nicola Marzari <span dir="ltr"><<a href="mailto:marzari@mit.edu">marzari@mit.edu</a>></span> wrote:<br>

<br>
One more suggestion - before ever using any thermostat, make sure your<br>
microcanonical run runs fine - total constant of motion absolutely flat,<br>
constant,<br>
and a ficitituious kinetic energy for the electrons at least 10 times<br>
smaller than<br>
the ionic kinetic energy. Make sure this happens, before doing anything<br>
else.<br>
