<div dir="ltr">Hi,<div><br></div><div>I do not know why this problem occurs, but it is not common (at least for me) to use so many scf steps... I expect to converge the wavefunction in 200 - 500 steps. Maybe if you change the CG for DIIS optimizer in the OT section it will be better. </div><div>Another thing is the initial configuration, you have some hydrogens of guest molecule so near to the MOF (some hydrogen or benzene rings). This situation could complicate the wfc optimization.</div><div><br></div><div>regards</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">El jue., 5 nov. 2020 a las 1:02, Monu Joy (<<a href="mailto:monuj...@gmail.com">monuj...@gmail.com</a>>) escribió:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:verdana,helvetica,sans-serif;font-size:13px"><div><div dir="ltr">Hi there</div><div dir="ltr"><br></div><div dir="ltr">I am trying to optimize a guest@host complex having 736 atoms where the host is a Metal-Organic Framework (HKUST-1) and the guest is a small molecule.
