多k点还是只有Gamma点?

KPOINTS文件用vaspkit生成的,内容如下:
KPT-Resolved Value to Generate K-Mesh: 0.040
If the occupancies are fixed by you, there should be a tag
FERWE = f1 f2 f3 ... f(NBANDS)
and for spin-polarized calculations
FERDO = f1 f2 f3 ... f(NBANDS)
in the INCAR file supplying the partial occupancies for all bands and k-points.

手册:
所以其他k点的占据情况也要写在里面。

老师您好,请问如果有多个K点,该怎么设置相应的FERWE和FERDO的参数
in the INCAR file supplying the partial occupancies for all bands and k-points. The band-index runs fastest. The partial occupancies must be between 0 and 1 (for spin-polarized and non-spin-polarized calculations).
Mind: Partial occupancies are also written to the OUTCAR file, but in this case they are multiplied by 2, i.e. they are between 0 and 2.

手册这段话要好好看:
The band-index runs fastest.的意思是说先循环每个能带的占据,再是不同的k, ...

好久没登录了,多个k点确实是循环写这个占据情况,谢谢老师。

您好,这个手册在哪里可以看到
smalll_wu 发表于 2022-10-20 20:37
手册中可能不明显,我之前没找到。不过你可以试试在k点为2*1*1时,把1*1*1时的参数循环一遍,这样应该就 ...

谢谢您的指点,如果说K点是2*2*1时,FERWE=5*1 4*0 5*1 4*0 5*1 4*0 5*1 4*0就要写成这样吗,“5”和“4 ...
