[交流] 【求助】band structures using hybrid functionals 的Kpoints问题

http://cms.mpi.univie.ac.at/vasp-forum/forum_viewtopic.php?4.6633.10
band structures using hybrid functionals have to be calculated the following way:
-) First perform a selfconsistent Hartree-Fock/HSE calculation using a conventional KPOINTS file.
-) Copy the IBZKPT file to KPOINTS, and explicitely add all desired k-points along high-symmetry lines of the BZ that are needed for the bandstructure plot. Add the points at the end of the KPOINTS file, but set the weights of these added k-points to 0.
-) Do not forget to set the number of k-points in KPOINTS correctly (to the number of the k-points used in the standard mesh PLUS the number of the k-points along the lines), such that all k-points are used for the calculations.
-) NKRED can not be used.
-) Perform a second VASP run:
It is recommended to use the Davidson algorithm, since it converges that eigen energies at the new k-points fastest. Since VASP terminates when the total energy is converged to a certain threshold, it is important to force VASP to do a minimum number of steps, so that the orbitals at the new k-points are fully converged (note: since their weight is zero, they do not contribute to the total energy).
This can be done using e.g.

ALGO = N ; NELMIN = 5 ! Davidson, minimum 5 scf-steps
IBRION = 1 ! Use simple charge mixer, since
Pulay might blow up

-) The KS-eigenvalues of the states along the high-symmetry lines are written in OUTCAR, EIGENVAL, vasprun.xml; please cut the k-points required for the bandstructure from one of these files and proceed as usual (using p4vasp or any other graphics tool you usually use to produce bandstructure-plots)

Note: A Hartee-Fock calculation can NOT be continued from an existing CHGCAR file, since the non-local exchange is not determined by the charge density but by the density matrix and/or the KS-orbitals.

以上是官方给出的解释。


我的问题是：
1、-) Copy the IBZKPT file to KPOINTS, and explicitely add all desired k-points along high-symmetry lines of the BZ that are needed for the bandstructure plot. Add the points at the end of the KPOINTS file, but set the weights of these added k-points to 0.
按照这样的方法产生的Kpoints运行后提示Kpoints错误，不能读取。
2、这一句不知所云：(to the number of the k-points used in the standard mesh PLUS the number of the k-points along the lines), 没有理解怎么回事？


请问谁用hse的方法计算过能带结构，请show一下下你的Kpoints。
谢谢。

在一楼你贴的那个官方回答里边说的很明白
-) First perform a selfconsistent Hartree-Fock/HSE calculation using a conventional KPOINTS file.
第一遍运行就是HSE自洽运算，而非普通的DFT运算。

IBZKPT
是单机产生的？

例子，上半部分是Monkhorst Pack产生的K点，下面是高对称的K点，第二行总K点的数目是两部分的总和，画能带的时候只取下面高对称部分的本征值即可
