Hi everyone!
I calculate chelates adsorbtion on graphene, within bivalent metal's ion, using tag NELECT=2. But calculations of single charge particle (Me2+) doesn't converge. Can somebody explain me the reason?

Me2+, NELECT=2 must be Sn2+ or Pb2+. Is this what you want to calculate?

Not exactly - I need to calculate Co2+. What could you recommend?
Regards,
Alice

Co has 9 valence electrons (ZVAL in POTCAR)). NELECT = 7 makes it Co2+

How can we use NELECT for the alloy system? For example: In my system there are two differently charged Fe atoms (Fe+2 and Fe+3) alloying with Oxygen.
