LAECHG = .TRUE. | .FALSE.
Default: LAECHG = .FALSE.
Description: when LAECHG=.TRUE. the all-electron charge density will be reconstructed explicitly and written out to file.
If LAECHG=.TRUE. is set VASP will reconstruct the all-electron charge density on the so-called "fine" FFT-grid.
The "fine" FFT-grid consists of NGXF×NGYF×NGZF points in real space, and is the same FFT-grid that is used to represent the augmented pseudo charge densities of the USPP and PAW methods.
