I deliberately added quotes, as everything depends upon what you are trying to do! I don't know for certain, but I would wonder about whether +U or -eece is needed for the Fe -- in which case your are obtaining converged results to a not so good model if you just use PBE or PBEsol (for instance).....</div><div class="yiv5496116703gmail_extra"><br><div class="yiv5496116703gmail_quote">On Tue, Jul 17, 2018 at 7:42 AM, Nacir GUECHI <span dir="ltr"><<a rel="nofollow" ymailto="mailto:guechiphy@yahoo.fr" target="_blank" href="mailto:guechiphy@yahoo.fr">guechiphy@yahoo.fr</a>></span> wrote:<br><blockquote class="yiv5496116703gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
