<div>Hi Matt</div><div><br /></div>Thanks for the answer, I also thought a surface dipole correction without vacuum did not make sense. <div>So is it correct then to ignore enabling the <a href="https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT.html#CP2K_INPUT.FORCE_EVAL.DFT.SURFACE_DIPOLE_CORRECTION">surface dipole correction </a>in a fully solvated system or is there some other way to correct for possible periodic artefacts?<div><br /></div><div>Kind regards</div><div>Léon</div><div><br /></div></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Wednesday 17 April 2024 at 10:05:02 UTC+2 Matt Watkins wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Applying a dipole correction self consistently in the calculation only makes sense with a vacuum present.<div>There are energy correction terms arising from dipoles that can be applied in many situations to account for periodic artifacts.</div><div>Matt<br><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Monday 15 April 2024 at 09:54:21 UTC+1 Léon Luntadila Lufungula wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Dear all,<div><br></div><div>I'm looking for an answer to a simple (and probably stupid) question. </div><div><br></div><div>I know that you need to set up a dipole correction when modeling a slab in vacuum with 3D periodic boundary conditions, but I was wondering if this is also necessary when the vacuum is filled with solvent molecules? From what I understand, the dipole correction is performed in the vacuum region and results in a flat profile of the electrostatic potential plot inside the vacuum region (apart from the region where the correction is applied) as you would expect for such a plot in the vacuum region. So a dipole correction seems incorrect adn ill-defined in a system without vacuum, however, I have heard from several people that they do apply a dipole correction even in a solvated system... Perhaps they used a different type of solvated system where there is still a vacuum region present (i.e., a vacuum-solvent-slab-solvent-vacuum box)?</div><div><br></div><div>Kind regards,</div><div>Léon</div></blockquote></div></blockquote></div>
