LDAU

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

Description: LDAU=.TRUE. switches on the L(S)DA+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 selfconsistent run. The deviations are often large for L(S)DA+U calculations. For the calculation of band structures within the L(S)DA+U approach, it is hence strictly required to increase LMAXMIX to 4 (d elements) and 6 (f elements).
