How to include AM05 functional in VASP calculation?

 In VASP calculation, the exchange-correlation is defined by the pseudopotential used. To select the specific type of exchange-correlation, use GGA=TAG.

VASP provides follwing GGA functionals.

GGA = 91 | PE | RP | PS | AM

To include AM05 functional in your calculation, just use PBE PAW potentials. Then, in the INCAR file, use:

GGA =AM     (for AM05)

Note: The tags AM (AM05) and PS (PBEsol) are only supported by VASP.5.X.
