<div dir="ltr">And in fact time taken using PAW is more than the US. For instance, the time taken by the US for a particular calculation was around 15-20 seconds which is around 1 minute for PAW. Is this normal? Or am I wrong anywhere?<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Dec 24, 2020 at 12:38 PM Pooja Vyas <<a href="mailto:poojavyas595@gmail.com">poojavyas595@gmail.com</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"><div>So far till now I have been using ultrasoft pseudopotential for my calculations and recently for the first time I switched to PAW pseudopotential.
