Dear all,

I want information of total energy of the system considered in VASP.
From the information of 'EALLAT' corresponds to
'total energy of all atoms'.
So I guess the total energy of the system in VASP is evaluated as
'energy(sigma->0)' - 'EATOM'
in OUTCAR file.

Do you agree ?

the total energy of the system (internal energy U) is energy(sigma->0)

Thank you for reply.

But, I was understanding about the energy differently
because in VASP the GUIDE

----------------------------------------------------------------------
The first values is the total free energy F (at this point the energy of the reference atom has been subtracted), E0 is the energy for sigma->0
----------------------------------------------------------------------

I forgot the place written about reference atom.
As I remember, energy of reference atom is for spin neutral.
Therefore I thought the energy written in OUTCAR file is
"spin uncorrected binding energy".
Energy calculated sigma->0 is basically same I think.

Isn't it right ?
