Energy without entropy vasp

WebWhat is the correct energy in a VASP calculation? energy without entropy = -3.08095641 energy (sigma->0) = -3.08142087. Which one of the two values should I consider and what will be the rationale for choosing that value? The short answer is that you want to use the latter (sigma->0). WebMay 23, 2006 · i did read that section and I understand about insufficient degrees of freedom, but my confusion is that the correct value is above the incorrect value. If I use the Davidson approach, I can see how I can converge to an excited state, i.e. too high an energy, but I could not get too low an energy.
