<div>Dear Ruvini,</div><div>In principle, you achieve this change by adjusting your &XC-section to</div><div> &XC</div><div> # THis sets the correct scaling factors of the different functionals<br /></div><div> &XC_FUNCTIONAL B3LYP
<div> &END XC_FUNCTIONAL</div>
</div><div> &HF</div><div> &INTERACTION_POTENTIAL</div><div> # CP2K employs by default the Coulomb potential which is not applicable in condensed phase<br /></div><div> POTENTIAL_TYPE TRUNCATED</div><div> # set it to a value a bit less than half the distance to the nearest neighbor</div><div> CUTOFF_RADIUS 4.99<br /></div><div> &END INTERACTION_POTENTIAL<br /></div><div> &END HF</div><div> # For the D3 correction<br /></div><div> &VDW_POTENTIAL</div><div> POTENTIAL_TYPE PAIR_POTENTIAL</div><div> &PAIR_POTENTIAL</div><div> TYPE DFTD3</div><div> REFERENCE_FUNCTIONAL B3LYP<br /></div><div> &END<br /></div><div> &END<br /></div><div> &END XC</div><div>In addition, you should use the B3LYP-optimized pseudopotentials instead of the PADE-versions (Replace GTH-PADE-q* by GTH-B3LYP-q*). Alternatively, you may employ the GTH-HYB-q* pseudopotentials in the POTENTIAL_UZH file.<br /></div><div>Beware that calculations with hybrid functionals are significantly more expensive (computation-wise and memory-wise) than calculations on the LDA or GGA level of theory. For that purpose, consider the Auxiliary Density Matrix Method (ADMM) by activating the &AUXILIARY_DENSITY_MATRIX_METHOD section in the &DFT section (see manual https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT/AUXILIARY_DENSITY_MATRIX_METHOD.html and the regtests for the information on the setup).</div><div><br /></div><div>Best,</div><div>Frederick<br /></div><div><br /></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">Ruvini Attanayake schrieb am Montag, 15.
