Hi rongzhi<div><br /></div><div>whether or not the temperature fluctuations that you observe affect the reliability of the simulation strongly depends on the specific system. </div><div>The method that you are using requires fine tuning of parameters, which are system dependent as well. This means running several preliminary simulations varying the relevant parameters until stability of temperature and energy are achieved. </div><div>Refer to literature for more details. </div><div><br /></div><div>Regards</div><div>Marcella<br /><br /></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Friday, January 26, 2024 at 8:22:39 AM UTC+1 marong...@gmail.com wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Dear all,<div><br></div><div>When I used CP2K to do the SGCPMD calculations, I observed that the temperature fluctuated by about 80K, with an average temperature of 330K, which was higher than the 300K temperature I expected. </div><div><br></div><div>I sincerely seek your advice as to whether this temperature fluctuation would adversely affect the results of my calculations. </div><div><br></div><div>Thank you very much for your assistance.<br></div><div><br></div><div>rongzhi</div><div><img alt="temperature_plot2.png" width="534px" height="401px" src="https://groups.google.com/group/cp2k/attach/30e81371097a2/temperature_plot2.png?part=0.1&view=1"><br></div></blockquote></div>
