LDAU = .TRUE. | .FALSE.
Default: LDAU = .FALSE.

Description: LDAU=.TRUE. switches on DFT+U.

Note on bandstructure calculation: The CHGCAR file contains only information up to angular momentum quantum number $l$ =LMAXMIX for the on-site PAW occupancy matrices. When the CHGCAR file is read and kept fixed in the course of the calculations (ICHARG=11), the results will be necessarily not identical to a self-consistent run. The deviations are often large for DFT+U calculations. For the calculation of band structures within the DFT+U approach, it is hence strictly required to increase LMAXMIX to 4 ( $d$ elements) and 6 ( $f$ elements).
