Hi,<div><br /></div><div>Thanks for your reply!</div><div><br /></div><div>Actually, the input settings follow a JACS Au paper on the Au/NaCl interface without smearing. And OT method is required for applying periodic external electric fields. I suspect the slow SCF convergence is related to the use of historical information in cp2k, but i haven't found any useful info on it so far.</div><div><br /></div><div>Best regards,</div><div>Yinyu</div><div class="gmail_quote"><div dir="auto" class="gmail_attr">在2026年4月10日星期五 UTC+8 15:44:09<Shiyang Wang (W0728)> 写道:<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>Hi,</div><div><br></div><div>I have doubt if your system is fit for OT method; it looks like to be metal-based and may require smearing.</div><br><div class="gmail_quote"><div dir="auto" class="gmail_attr">在2026年4月9日星期四 UTC+8 19:18:49<Yinyu chan> 写道:<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 CP2K community,<div><br></div><div>I'am a new user of CP2K(v2026.1) and I'm running an AIMD simulation of a metal-electrolyte interface (Au-Pd alloy/NaCl(aq)) with electric field.<br></div><div><br></div><div>However, I encountered an issue where the SCF starts fast but then becomes slow, as shown in the *ener file.
