ELFCAR
The ELFCAR file is created when the LELF=.TRUE. in the INCAR file is set and contains the so-called ELF (electron localization function).
Available up from VASP version 3.2.
The ELFCAR file has the same format as the CHG file. It is recommended to avoid wrap around errors, when evaluating the ELFCAR file. This can be done by specifying PREC=High in the INCAR file.
