[求助] WIEN2k+BolTzTraP做自旋极化时,自洽总能合成问题请教!

以前没做过自旋极化的计算,现在在合成能量上出了问题:

自旋极化计算自洽分能量有case.energydn_??和case.energydn_??的分能量各20个,
1.Boltztrap 用的总能怎么合成?
2.我改进了下gather_energy.pl程序,原始代码是做耦合的代码,我在这里改动了下:
WIEN2k+BolTzTraP做自旋极化时,自洽总能合成问题请教!
3.改动后下:

WIEN2k+BolTzTraP做自旋极化时,自洽总能合成问题请教!-1

4.但是不知这样做行得通不?

自旋极化情况下,合并成两个文件energyup和energydn,那然后呢?在Boltztrap计算时,分别计算up和dn的?还是up和dn的还要再合并一下呢?
我看到相关文献,对于磁性的化合物输运结果并没有up和dn两个结果啊,只有一条曲线,里面也没有说怎么考虑的自旋极化的情况。

Hi Gavin

Thanks it works...

Thanks for your input...
