<div dir="auto">Electronic structure coordinates are burai generated which is gui for quantum espresso. One of my friend has generated melt using that electronic structure in quantum espresso and now performing the quench run. I have used low cutoff for less computational cost. I have set pw cutoff to 300 which is default in cp2k. Do i have to set high cutoff? </div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 20 Dec, 2023, 8:13 pm Marcella Iannuzzi, <<a href="mailto:marci.akira@gmail.com">marci.akira@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><br></div>I suppose in that previous work they managed to get a reasonable electronic structure before running AIMD<div>If you have same coordinates and simulation cell, you should also be able to reproduce their results.</div><div>However, if the coordinates are not consistent with the simulation cell, there are for sure problems. </div><div><br></div><div>In the paper the only information about the settings are basis set, functional and PW cutoff, that by the way is 600 Ry and not 300.</div><div>Other settings and parameters might need to be adjusted. </div><div><br></div><div>Regards</div><div><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Wednesday, December 20, 2023 at 1:43:43 PM UTC+1 <a href="mailto:vahiyam...@gmail.com" target="_blank" rel="noreferrer">vahiyam...@gmail.com</a> 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"><div dir="ltr">Thank you for your response.<br>I've not checked electronic structure calculation but for aimd simulation I referred to one paper in which they have done the same thing which is to simulate an amorphous system of ZrCu.

Now I want to generate an amorphous structure. So I've used an annealing parameter. As in the annealing process we can not use a thermostat. So we can not apply an ensemble which has a thermostat. So I started the run but the temperature is going out of control. Is there any other parameter i have to set in the file. I've attached the input and ener file for reference.</div></div>
