关于vasp+boltztrap

现在的最新的BoltzTraP 1.2.5已经很支持vasp接口了,
在压缩包“util”文件夹里有vasp2boltztrap.py和vasp2boltztrap.txt两个文件
在系统上已经安装好ase(https://wiki.fysik.dtu.dk/ase/)的基础上

根据需要修改vasp2boltztrap.txt中的
# Example 1:
#sg = Spacegroup(1)
#ao.info = {'spacegroup': sg}

# Example 2. Here the unit cell in the POSCAR file is cubic (conventional):
sg = Spacegroup(122)
ao.info = {'spacegroup': sg, 'unit_cell': 'conventional'}

并将vasp2boltztrap.txt 改名为a.py
执行命令python a.py
显示
********
None

输出的 energies.boltztrap,struct,intrans,可以用于boltztrap计算
hello,boy~

Hi Gavin

Thanks it works...

Thanks for your input...

error in factorization while executing BoltzTrap
引用回帖:
Maybe the BoltzTraP interpolation scheme (src/fite4.F90) has failed because your k-mesh is too course. You could try increasing the number of k-points to create a fine k-mesh (x kgen) followed by regenerating case.energy[up/dn] (x lapw1 [-up/-dn]) before running BoltzTraP again (path-to-BoltzTrap/x_trans BoltzTraP[-up/-dn]).

楼主这是好贴,但是之提到了intrans文件,没有提到condtens中与它对应的各项异性的文件,我用的是 wienk,要是嗯呢个知道这些数据该怎样处理就好了,说明书里没有,我找了好久也没找到,不明白相关的各种图形都是i怎么提取怎么做的,希望可以请教您。
愿不负最苦的时光
