writing wavefunctions

The example output (stdout) for the O atom was obtained using VASP version 5.4.1. The initial charge corresponds to the charge of isolated overlapping atoms (POTCAR file). For the first 4 steps the charge remains fixed, then the charge is updated (rms(c) column)

Short explanation of the symbols in the OSZICAR and stdout file:

N iteration count
E total energy
dE change of total energy
d eps change of the eigenvalues (fixed potential)
ncg number of optimisation steps
rms total residual vector
rms(c) charge density residual vector
