Hello,
As I recall, it is nonessential to change the value in case.inst. But the
change of NE in case.in2 is important.
It is straight to do so — when you change Fe 26 to 26.2 in case.struct, add
0.2*number of Fe (in the considered unit cell) to the existing NE.
The reason is simple --- With 26 to 26.2, the valence electron count is
increased.
Cheers,
Jianxin

Subject: [Wien] virtual crystal approximation
Dear all,
I want to do virtual crystal calculation. I change Fe’s Z to 26.2. I also
change case.inst to:
Fe
Ar 3
3, 2, 2.0 N
3, 2, 2.0 N
3, -3, 2.5 N
3, -3, 0.0 N
4, -1, 1.0 N
4, -1, 0.7 N
I checked the Mail Archive. Someone said I also need change NE in case.in2. I
do not know how to change it, and why I need change NE. I also do not know NE’s
means. Could you tell me. Thank you.
Best,
Qingping Meng
