<div dir="ltr">Hi, <div><br></div><div>It seems to me you have a convergence problem. So you have to first choose a reasonable cutoff value and the basis set, and the functional as well, before MD calculations.</div><div><br></div><div>Plz read the follow instructions:</div><div><br></div><div><a href="https://www.cp2k.org/howto:converging_cutoff">https://www.cp2k.org/howto:converging_cutoff</a> </div><div><br></div><div><a href="https://www.cp2k.org/exercises:2018_uzh_cmest:faq">https://www.cp2k.org/exercises:2018_uzh_cmest:faq</a></div><div><br></div><div>You get a lot of work to do!</div><div>Good luck~<br></div><div>Haibei</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">冬tlyer <<a href="mailto:tsd19...@gmail.com">tsd19...@gmail.com</a>> 于2020年10月6日周二 上午11:42写道:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello haibei,<div> </div><div>Thanks for you reply.</div><div>I can get your meaning "constrain bood length". But i try another input file in my system, the decomposition did not occur again. And i complare the twe file finding that the some differenence is the QS section , the XC_GRID and the MG_GRID. So in my mind ,maybe these sections get the AIMD to different output. However, i don‘t know what section solve the situation of decomposition.</div><div><br></div><div>As for fix bood length , I feel it will cause errors in the calculation results . But this is only my feelling.</div><div><br></div><div>The new input-file and the old input-file as attach is present below.</div></div>
