<div dir="ltr">Dear Dr Kumar<div><br></div><div>Thank you for your reply. Actually, in publications related to 2D materials I find that a vacuum is applied in perpendicular direction to the plane of nanohseet, say graphene. In vc-relax the change in dimension may affect the vacuum thickness. I there any option to address this? What about esm?</div><div><br></div><div><br></div><div>ThanksĀ </div><div>Rajesh</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jul 24, 2017 at 3:39 PM, Sonu Kumar <span dir="ltr"><<a href="mailto:1009ukumar@gmail.com" target="_blank">1009ukumar@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small">Relax will only relax your atomic positions, while vc-relax will relax atomic positions<br></div><div class="gmail_default" style="font-size:small">as well lattice parameters.
