OK, here is Update. Actually I'm testing ECP with V2O5 crystall 1x3x2 Supercell. Now when I switch to GTH pseudopotential I have the following initial values for number of MO:<div><i> Total number of - Atomic kinds: 2<br> - Atoms: 84<br> - Shell sets: 84<br> - Shells: 684</i><br>There are 24 V atoms and 60 oxygens. I.e. total number of shells is: (24*13+60*6)=672 (for V there is 13 valence electrons for O it's 6). Which is different then 684 for some reason.</div><div>In case of ECP the numbers are:</div><div> Total number of - Atomic kinds: 2<br> - Atoms: 84<br> - Shell sets: 336<br> - Shells: 192<br></div><div>Well, Huston we have a problem. How to resolve the issue?</div><div class="gmail_quote"><div dir="auto" class="gmail_attr">понедельник, 7 февраля 2022 г. в 19:30:11 UTC+3, Eugene: <br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">According to cp2k documentation <a href="https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/SUBSYS/KIND.html#POTENTIAL" target="_blank" rel="nofollow" data-saferedirecturl="https://www.google.com/url?hl=ru&q=https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/SUBSYS/KIND.html%23POTENTIAL&source=gmail&ust=1644344452815000&usg=AFQjCNH-e2exVhsWMXDsM9_zaJaID2mgxQ">https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/SUBSYS/KIND.html#POTENTIAL</a> it is possible to set POTENTIAL variable value as ECP, in order to use Effective core potential.
