<p style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Dear CP2K Community,</p><p style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">I am currently working on optimizing an organometallic complex (and a metalloenzyme) that contains europium (Eu2+/Eu3+), but I have encountered issues with wavefunction convergence. Despite testing various combinations of pseudopotentials and basis sets, I have not been able to achieve convergence.</p><p style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">I would appreciate any advice regarding suitable pseudopotentials and basis sets for europium or suggestions for specific convergence parameters that might improve stability. Additionally, if there are particular settings or methodologies that have proven effective for similar systems, I would be grateful to learn about them.</p><p style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Thank you for your time and assistance. </p>
<p></p>
