I did use the same cutoff (35 and 350) of course. I just managed to copy<br>
and paste the wrong input file for isolated water... I will see if the<br>
the nosym and assume_isolated makes a difference.<br>

&gt; Hi Martin,<br>
&gt; Just a quick note,<br>
&gt; when calculating isolated molecules, set nosym = .true. not to use any<br>
&gt; symmetry, set some form of assume_isolated for polar molecules to<br>
&gt; account for periodic image corrections. i dont know if these would<br>
&gt; affect your results but this is the correct way of accounting for an<br>
&gt; isolated system in a periodic code.<br>
&gt;<br>
&gt; Also, definitely important:<br>
&gt; compare things in the same level of accuracy: ecutwfc, ecutrho etc.<br>
&gt; should correspond to the same level of expansion in plane waves both<br>
&gt; in water molecule and amorphous ice/water complex..keep them the same.<br>
&gt;<br>
&gt; hope this helps<br>

&gt;&gt; Hi,<br>
&gt;&gt;<br>
&gt;&gt; I have been calculating the cohesive energy of amorphous ice as well<br>
&gt;&gt;   as ice/water layers on mineral surfaces with the PBE functional. I<br>
&gt;&gt; get a cohesive energy for water in amorphous ice (144 waters in a<br>
&gt;&gt; ~16x16x16 Å box) compared to water in a 20x20x20 Å box that is 1.08<br>
&gt;&gt; eV for ultrasoft pseudopotentials (35 Ry cutoff) (the rrkjus ones<br>
&gt;&gt; from the library) and 0.98 for PAW (50 Ry cutoff) from the AtomPAW<br>
&gt;&gt; library. This is significantly different from other studies in<br>
&gt;&gt; literature, who find around 0.7 for PBE and PW91. I have no idea on<br>
&gt;&gt; why results differ so much, so any suggestions are welcome... Input<br>
&gt;&gt; files below<br>
&gt;&gt;<br>
&gt;&gt; I have used QE 4.2.1 for the calculations.<br>
