Dear CP2K community,<div><br /></div><div>I tried to calculate the XPS binding energy of some O atoms on a Pt slab with the delta SCF method. Ideally I wanted to use a big all electron basis for the interested O atoms, a small all electron basis for other O atoms, and DZVP-MOLOPT basis for Pt with pseudopotential. I concatenated ALL_POTENTIALS and GTH_POTENTIALS together for the potential used for the calculation. However, the delta SCF calculations failed to converge. I tried as well the ground state calculation, with GPW method, the calculation managed to converge; but with the GAPW method and all electron basis, it never converges and finally return an absurd energy value. In addition, both calculations had a warning about Fermi-Dirac smearing, despite I used METHFESSEL_PAXTON smearing and 1000 ADDED_MO. Do you have any suggestions or fix for the issue? Thank you.</div><div><br /></div><div>Best regards,</div><div>Hengyuan</div>
