Can you give us the xyz file?<br /><br /><div>I was initially going to suggest lowering the TIMECON under thermostat, but I am not confident that would be a way to see faster equilibration. I would also run it for a little longer before making conclusions - I will still let the experts speak!</div><div><br /></div><div>Michela</div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Friday, June 13, 2025 at 12:38:08 PM UTC-4 emerson p l 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;"><p>Dear CP2K community,</p>
<p>I was running an MD simulation (using the "cp2k-md.inp" file) and noticed a possible issue.</p>
<p>Two energy files are being generated. One is called "cp2k-md-1.ener", which I believe is the main one, and another called "cp2k-md-1.bener", which I believe is related to the barostat.</p>
<p>The simulation I'm running is at 450 K. The issue is that in the "cp2k-md-1.bener" file, the temperature seems to be controlled (i.e., it fluctuates around 450 K). However, in the "cp2k-md-1.ener" file, it starts at 450 K but decreases and seems to fluctuate around ~250 K.</p>
<p>Could there be something wrong with my script? Or did I misunderstand what each file represents?</p>
<p>Thank you in advance.</p><p>Best,</p><p>Emerson</p></blockquote></div>
