Just bumping this again. Hoping someone could chime in with their experience with CP2K and the external potential function and how it is applied.<div><br /></div><div>Thanks!<br /><div><br /></div></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Thursday, September 21, 2023 at 9:45:50 PM UTC-4 Dev Rana 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;">Hi All,<div><br></div><div>I had a theoretical question regarding the electric potential that is applied in CP2K.</div><div><br></div><div>Let's say that a simulation box has a electric potential gradient applied to it in the +x-direction: electric potential gradient = 2X</div><div><br></div><div>If you have positively charged ions (cations) and negatively charged ions (anions), which direction would they flow in relation to the electric potential gradient within CP2K?</div><div><br></div><div>Do cations flow in the direction of the gradient (+x-direction) or against the gradient (-x-direction)?<br></div><div><br></div><div>The way that CP2K applies the gradient is 2x, meaning that further away (x=10), the potential is 20 and nearer (x=1) the potential is 2.
