NWRITE = 0 | 1 | 2 | 3 | 4
Default: NWRITE = 2

Description: This tag determines how much will be written to the file OUTCAR ('verbosity tag').

The options for NWRITE are given in detail as

NWRITE	0	1	2	3
contributions to electronic energy at each electronic iteration	f	f	e	e
convergence information	f	f	e	e
eigenvalues	f+l	i	i	e
DOS + charge density	f+l	i	i	e
total energy and electronic contributions	i	i	i	i
stress	i	i	i	i
basis vectors	f+l	i	i	i
forces	f+l	i	i	i
lattice and space group information for ISYM>0	f	f	f	f
symmetry operations for ISYM>0				f
timing information			X	X

where the following abbreviations have been used

f+l	first and last ionic step
f	first ionic step
i	each ionic step
e	each electronic step
X	when applicable

Tip: For long molecular-dynamics runs, use NWRITE=0 or NWRITE=1. For short runs use NWRITE=2. NWRITE=3 might give information if something goes wrong.

NWRITE=4 is for debugging only.
