[Wien] no effect in shifting of f bands on application of hubbard U

2013-01-02 Thread Pooja Rana
Respected Prof. Blaha and dear WIEN2k users,
Wish u all a very happy, prosperous and promising new year.

I have countered with a problem related to rare earth intermetallics metallic 
in nature.
I have computed eletronic band structure by GGA, GGA+U and GGA+U including Spin 
orbit coupling but no effect found in the three set of calculations.

I have repeated the task number of time for different values of U, but still f 
electrons showed their concentration near fermi level around -4 eV.

Is it possible that U have no effect in some compounds??
If not then please suggest me some solutions to get rid of this problem?

Hope for the earliest reply,

With kind regards and thanks,

[Wien] problem regarding PDOS

2012-02-16 Thread Pooja Rana
Respected Prof. Blaha and all dear Wien2k users,

A very Good after noon to all.

During calculations for PDOS, a problem QTL not supported occurs, due to 
which i am not able to get the PDOS.
?I have already successfully calculated the PDOS for the various systems 
without any such type of problem. 
I have tried with new directory and with new calculations in order to resolve 
the problem for several times but it doesn't works.

Kindly give me some suggestions how to get rid of this problem.

Many thanks in advance,

with regards,

[Wien] problem during visualisation supercell structure

2011-06-13 Thread Pooja Rana

Respected Prof. Blaha and dear Wien2k users,

The structure of supercell has been generated successfully but their is problem 
to visualise the position of the doped atom using X-crysden.
The dopent is not appeared in the structre and X- crysden windows shows the 
same structure as for pure compound.

Please suggest how to resolve the problem and to get the dopent position.

Respected Prof. Blaha and dear Wien2k users

I am facing problem with lapw1 during scf of supercell in NaCl structure.
The error as:
lapw1.error
 'SELECT' - no energy limits found for L= 2
 'SELECT' - E-bottom -200.0   E-top -200.0 

I have tried all corrections in related files and also checked the structure 
file, it is generated successfully  without any error. I have also done 
supercell calculations with zincblende structure, without any such type of  
error.

Please guide my by your suggestions , how to rectify the problem.

Many  thanks

[Wien] problem regarding supercell

2011-04-23 Thread Pooja Rana
Respected Prof. Blaha and dear WIEN2K users,

Presently I am trying to define a supercell  for Na(1-x) K(x) Cl type of 
compound with fcc structure (225 Fm-3m). But I am able to create the supercell 
but unable to define impurity position and composition ( x= 0.05, 0.1, 0.15, 
0.2,  ). 

If I  define the structure for Na and Cl only and created a supercell of 8 
atoms 
and introduce an impurity in one of the Na atom then it gives error   atom #1 
and atom #3 coincide.

Should I  define three atoms  for Na , K, Cl simulatanoeusly during the 
structure generation with positions of Na , K, Cl ?
When I did so, I got error in dstart unit 15 ( case.in2c) can not be opened.

Regards and thanks,
