Hello Everyone,
I am wondering how to calculate the zero point energy ? Or is it included in the total energy EO in the OUTCAR file ?
Thank you

For a periodic system you need to calculate the phonon density of states. See the discussion here:

For an isolated molecule you need to do the vibrational analysis, just like any other quantum chemistry approach.
