For reference, check our manual (<a href="https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT/XC/WF_CORRELATION.html" rel="nofollow" target="_blank" data-saferedirecturl="https://www.google.com/url?hl=de&q=https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT/XC/WF_CORRELATION.html&source=gmail&ust=1647530264145000&usg=AFQjCNGWf9NtqPn207tKv9f_Drn8-Qwbug">https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT/XC/WF_CORRELATION.html</a>). The major changes are</div><div>- remove the METHOD keyword</div><div>- move the CPHF section into the RI_MP2 section</div><div>- wrap the WFC_GPW section into an additional INTEGRALS section</div><div><br></div><div>Furthermore, remove the RI_AUX_BASIS_SET keywords in the KIND sections and use something like 'BASIS_SET RI_AUX RI_TZ'.</div><div>If you use the CP2K trunk, replace the LIBXC section with functional <your-libxc-functional> by a section of name
<your-libxc-functional>. The manual will tell you all available functionals and their parameters.</div><div><br></div><div>HTH</div><div><br></div><div>Frederick<br></div><br><div class="gmail_quote"><div dir="auto" class="gmail_attr">Thorren Kirschbaum schrieb am Mittwoch, 16.
