<div>Hello, <br /></div><div>You could try to use Orbital Transform, it should give a nicer convergence in your case. Broyden mixing may not be the best method in your case. If you cannot use orbital transform, you may increase damping in the broyden mixing (alpha 0.1 to 0.01). </div><div>You can find some resources on helping convergence on the CP2k website, including input snippets for OT and mixing:</div><div>https://www.cp2k.org/_media/events:2016_summer_school:20160824_scf.pdf</div><div>Take care :)</div><div>Q.</div><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">Le vendredi 7 février 2025 à 15:00:19 UTC+1, Naina Sethi a écrit :<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>I have a dimer molecule in which two Cr(III) centers are present and bridged by a thiosemiquinoid ligand.
