[Wien] Virtual-crystal

[Jihoon Park]

Dear Users,


I am trying to perform a calculation using "virtual-crystal" method.
I have found the way to do this and it is as below.

- run through inil_lapw using default atomic numbers
- edit nuclear charges in case.struct
- edit corresponding occupancies in case.inst
- edit the total number of electrons in case.in2
- run SCF circle


But I do not understand a few things.

First, I do not know how I should change the occupation number. I have looked up the manual, but still confused. 
Just say that I want to do x = 0.5 for example, then what should I edit? There are numbers like "1.0, 2.0, 3.0 and so on..."

Second, if I want to add one more electron in the unit cell (two f.u., therefore x = 0.5), should I just do the # of electron + one in case.in2?
For example, if the current # of electrons is 25, should I put the # of electrons as 26?


All my best,
Jihoon Park
