Hi,
I am doing calculations with the LAECHG flag.

I am wondering what is the difference between the CHGCAR file
and the file AECCAR2?

Thanks for your answers.

I cant tell from the source code a 100%
but are the CHGCAR and AECCAR2 related
by equation (3) from Kresse, Joubert, PRB 59, 1758 (1999) ?
