<p>Dear CP2K Developers,</p><p>I am currently trying to calculate the Hubbard U parameter using the linear response approach in cp2k for a DFT+U setup. I have successfully obtained the occupations from the self-consistent response. However, I am struggling with how to obtain the non-self-consistent response occupations.</p><p>Specifically, I am trying to perform a calculation where only the electron density and occupations are updated without performing a full SCF iteration, in order to obtain the non-self-consistent occupations. I couldn't find a way to achieve this in cp2k. Could you please advise on how I can configure cp2k to only update the electronic density without running a complete SCF?</p><p>Any guidance or examples of input parameters to perform this type of non-SCF calculation would be immensely helpful.</p><p>Thank you very much for your assistance.<br /><br />Here is some reference of linear response approach:<br /><a href="https://doi.org/10.1103/PhysRevB.71.035105" style="box-sizing: border-box; border-width: 0px; border-style: solid; text-decoration-line: underline; text-decoration-thickness: inherit; text-decoration-style: inherit; text-decoration-color: inherit; display: inline; align-items: center; gap: 0.25rem; word-break: break-all; font-family: "Noto Sans", Helvetica, ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji";">https://doi.org/10.1103/PhysRevB.71.035105</a><br />https://www.vasp.at/wiki/index.php/Calculate_U_for_LSDA%2BU</p><p>Best regards,<br />Luo Rong Hao  <br /></p>
