[交流] 【求助成功】DOSCAR中的信息不全,没有site-projected DOS已有9人参与

这是我以前算的一个结果,DOSCAR:

这是这次的结果,就只有开始的那三列总的,下面的那些分的态密度就没有。这是INCAR:
引用回帖:
System = CaFe2As2 ThCr2Si2 DOS
PREC = Accurate
ISPIN = 1
ISMEAR = -5 #for DOS,tethraedron method with Blochl corrections
SGIMA = 0.02
ISTART = 0
EDIFF = 10E-5
ICHARG = 2 #SC-calculation
#ISIF = 2 #stress and relaxation
NSW = 0 #for DOS, the steps of ions relaxtions
IBRION = -1 #for DOS, ions no update, not moved

LREAL = Auto #for supercell or largecell
LORBIT = 11
EMIN = -10 #energy-range for DOS
EMAX = 15
NEDOS = 3501 #number of grid kpoints DOS
ENLMDL = -5 #no update charge for 3steps
NELMIN = 2 #min of two steps
NELM = 60

LPLANE = .TRUE. #parallelisation for linux cluster
NPAR = 4 #number of nodes
LSCALU = .FALSE.
NSIM = 4

请问大家支招。

昨天看错了,我以为是没有设置NEDOS的问题呢,可是发现楼主的INCAR里是设置了的,本想删帖的,可是不知道怎么删,就只有修改了

如果没有设置的话,会使用默认值NEDOS=300的。
明察、慎思、笃行

The parallel version has some restrictions: The site projected DOS is not evaluated in the parallel version in the following cases:
VASP.4.5, NPAR 6 =1 no site projected DOS
VASP.4.6, NPAR 6 =1, LORBIT=0-5 no site projected DOS

引用回帖:
The wave function character is calculated, either by projecting the wavefunctions onto spherical harmonics that are non zero within spheres of a radius RWIGS around each ion (LORIT=1, 2), or using a quick projection scheme relying that works only for the PAW method (LORBIT=10,11,12, see below).

引用回帖:
If the projector augmented wave method is used, LORBIT can also be set to 10, 11 or 12. This alternative setting selects a quick method for the determination of the spd- and site projected wave function character and does not require the specification of a Wigner-Seitz radius in the INCAR file (the RWIGS line is neglected in this case). The method works only for PAW POTCAR files and not for ultrasoft or norm conserving pseudopotentials.

必须要NPAR=1,LORBIT=11或者12,必须要使用PAW方法,采用PAW势。试着改动一下。
