PBE or LDA) and is not applicable to Category:INCAR tag The INCAR file is the central input file. The units are number of states/eV and number of states, respectively and thus extensively defined. Specifically, one can use ALGO = TDHF 301也就是默认的NEDOS的取值。 如果我们设置的NEDOS值够大，那么DOS区间就会被区分地越精确。 NEDOS的取值一般来说：NEDOS = 3000左右就足够好了。 NEDOS越大，VASP I am trying to calculate Density of states (DOS) using VASP. Generate Input Files ¶ In order to perform a VASP calculation, usually one needs 4 files, INCAR, POSCAR, POTCAR and KPOINTS. One problem you will have is that VASP defaults to making the mim/max energy of the DOS as the entire range of the spectrum which you rarely care about.
