Dear CP2K experts<div><br /></div><div><span style="color: rgb(0, 0, 0); white-space-collapse: preserve;"> </span>I am trying to perform geometry optimization by fixing some atoms of adsorbate. The optimized structure will be used as initial guess for dimer calculation. After 5 steps of geometry optimization, the SCF cannot converge. The energy keeps jumping in SCF cycles. Recently I switch from Gamma point to KPOINTS with "<span style="white-space-collapse: preserve; color: rgb(0, 0, 0);">MONKHORST-PACK 2 2 1" to improve the accuracy of force evaluation, this issue happens since then.</span></div><div><br /></div><div><img alt="Screenshot 2024-10-23 113727.png" width="371px" height="536px" src="cid:07afec73-d9c2-4150-a4ce-62c2978b7c2f" /><br /><br />Input and output files are attached. Much appreciation if you can provide thoughts about this issue.<br /></div><div><br /></div><div>Thank you,</div><div><br /></div><div>Tian-Ning Chen</div>
