VASP Input files: INCAR
From EVOCD
The INCAR file is the central input file of VASP. It determines what to do and how to do it. It is a tagged format free-ASCII file: Each line consists of a tag (i.e. a string) the equation sign '=' and one or several values. Defaults are supplied for most parameters. A sample INCAR file contains the following 4 lines only:
IBRION = 2 ISIF = 3 LWAVE = .FALSE. LCHARG = .FALSE.
