<br><br><div>At the attention of the cp2k community,</div><div>I have done
with success several computation of the hydroxide ion on the Pd 111
surface. I want to do the same energy calculations for the hydroxyl
radical. In the attachment, you can find input, output and the
coordinate file. <br></div><div><br></div><div>The calculation with the
radical converges, but the message "WARNING: S**2 computation does not
yet treat fractional occupied orbitals" scares me. The output does not
recognize this warning as a warning, but I have spin contamination
because I am using the smearing. But I must use smearing because I have a
metallic surface.</div><div><br></div><div>I just need the energy, then
my question is: Is the obtained energy consistent with the calculations
done for the anion on the surface? Thank you for your time</div><div><br></div><div>Jonathan</div>
