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>
