Dear Sara<div><br></div><div>Before starting a geometry optimisation it is good practice to get a converged single point calculation. </div><div>If I understand correctly from the output you posted, this was not the case. </div><div><br></div><div>I played a bit with the settings for your system and I got a converged single point calculation at the PBE level of theory </div><div>for the molecule charged --2 (see the attached file).</div><div><br></div><div>Kind regards</div><div>Marcella</div><div><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Tuesday, September 13, 2022 at 4:00:25 PM UTC+2 salla...@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>I am having problems on a geometry optimisation of a heme group with Fe2+ using PBE in CP2K.
