Perhaps you mean a fixed point scf calculation, i.e. without updating the positions.<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="auto"><div dir="auto"><br></div><div dir="auto">When I do relax calculations do I need to do scf calculations also?<br></div></div></blockquote><div>It depends on what you want to do. Do you want to compute some quantity self-consistently? AFAIK, some calculations require a different parameter set WRT the relaxation.<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="auto"><div dir="auto"></div><div dir="auto"><br></div><div dir="auto">Thanks</div><div dir="auto">Malathe </div><div dir="auto"><br></div></div>
