[Wien] Query about nano calculation

2014-05-16 Thread K. K. Suthar
Respected Prof. Blaha and Wien users,
I want to do calculation for nano system like MoS2 and WS2 (nano powder of 
order of say 90 nm).
Can I do using this package. If yea, how?
With regards,

No, certainly not with a brute force simulation of a 90 nm particle.

[Wien] optimization internal positions

2014-05-16 Thread ben amara imen
Hello,

In order to optimize the internal position u, I have do these steps just
after the Initialization :

1) I have chosen 6 for change structures and 20 for iterations
2) job file : min_lapw
3) prepare commande
4) start it

Then, during the iterations I have this warning : overlapping spheres. I
have increased the Rmt value. But after some iterations  I have this error
:   *stop in mini, small force  *what means.??

 what I can do to overcome this probleme and  my steps are corrects???

Can someone help me Please and thanks in advance
