<div dir="ltr"><div>Semiempirical vdW corrections do not compute a vdW potential. For that you need nonlocal DFT functionals, activated by setting variable input_dft to some vdW-aware functional (e.g. vdW-DF, vdW-DF2). The nonlocal correction to the exchange-correlation potential is computed inside routine "nlc" but it is added to other terms of the XC potential and is not available anywhere else in the code.</div><div><br></div><div>Paolo<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Feb 1, 2021 at 10:26 AM 柯莫 <<a href="mailto:rajupdl6@g.ncu.edu.tw" target="_blank">rajupdl6@g.ncu.edu.tw</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello Everyone, Good Afternoon,<div>I want to calculate vdw potential seen by electrons in monolayer 1 tmdc due to charge density on the 2nd layer and vice versa. For this non-local-correlation contribution to the potential points on the grid on the surface is needed. I check in the Quantum espresso VDW-D3 directory there and I see only the improvement in energy not potential due to vdw interaction. Could you help me to calculate the vdw potential and related subroutine. Looking forward to your help.
