Marcella Iannuzzi <div> I have changed mixing temperature from 300K to 1000K don't work.As for ALPHA, my initial set is 0.1,when I try to increase its value to 1.0, it also can't convergence. Its energy jumps like this enve after 200 SCF steps or 5 Ion step.<br><img alt="" width="641px" height="506.837px"><br></div><div>but in vertical adsorption , it only costs 69 SCF steps in first step and 12 ion steps in total.</div><div><img alt="" width="523px" height="291.845px"><br></div><div><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">在2020年11月6日星期五 UTC+8 上午12:05:42<Marcella Iannuzzi> 写道:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><br></div>You provide very little information, it is difficult to judge. <div>Did you try changing ALPHA in mixing and the temperature in smearing? </div><div><br>Regards</div><div>Marcella</div><div><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Thursday, November 5, 2020 at 3:38:08 PM UTC+1 silencesola wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div>Dear CP2K users</div><div>I have got a surface of Ti2AlN, when I put a oxygen molecule on it with Vertical adsorption ,it's SCF convergences well.but when I put with parallel adsorption,SCF can't convergence.and I have try to change EPS_ DEFAULT, EXTRAPOLATION_ORDER, EPS_FILTER_MATRIX, EPS_PGF_ORB and MIXING section, but it's not useful. </div><div>I appreciate any comment which can help getting ride of this error.
