Hi Ari, yes, you can plot Vhartree or Vhartree_xc as they flattens out in the vacuum - first should be shorter ranged (see Caspar Fall PhD thesis). If you have a slab geometry, you can do a planar average in the directions parallel to the slab. Indeed, make sure it is flat - trickier if you

Hi Evan, regarding your question below, various times I had to extract the potential with the same parameters for pp.x AFAIK the units used in that case are ATOMIC RYDBERG UNITS, that means Rydbergs (Ry) for energy, and 1 Ry = 13.6057 eV Cheers >Hello, everyone >I output the potential

Dear Colleagues, I tried to search the FAQ and archives but was not successful - sorry if this is already answered somewhere. I am trying to calculate core level binding energies of atoms, and for this I need to align the total energies of the two calculations, with and without the
