To perform a DFT + U calculation using VASP you just have to add the following flags to your INCAR file:


GGA = PW | PB | LM | 91 | PE | RP | PS | AM (Depending on the functional you want to use)

LDAU = .TRUE.

LDAUL = 3 1

LDAUU = 5.5 0.0

LDAUJ = 1.0 0.0

LASPH = .TRUE.


NOTE: In VASP there are several DFT + U approaches that can be used. You can specify the one you want by setting the corresponding values in the flag LDAUTYPE = "value". The default approach in VASP is the one introduced by Dudarev et al. (LDAUTYPE = 2). For further details see VASP manual.
