<p class="MsoPlainText">Hi Juerg,</p><p class="MsoPlainText"><br></p>
<p class="MsoPlainText">thanks for your answer. The reason why the number of SCF iterations was set to 1
is, that I generated this input to converge the cutoff and rel_cutoff of large
systems (several hundrets of atoms, H2O is just a test system). This approach
was described in the HOWTO on cp2k homepage <a href="https://www.cp2k.org/howto:converging_cutoff">https://www.cp2k.org/howto:converging_cutoff</a>
. The probleme with my input is the large energy jump when increasing the
cutoff from 249 to 250 that appears with all systems I tested so far. To your energy
value: did you increase the number of SCF cycles or change anything else?</p>

<p class="MsoPlainText">Again thank you for your help.</p>
