Prof. Blaha:
I am executing the FSM calculation for gamma-Fe with lattice constants
a=b=c=3.56 ang.
Another values employed are:
RMT=2.2
ENERGY to separate core and valence states: -7.0 Ry
The case.in1 file is:
WFFIL (WFPRI, SUPWF)
8.00 10 4 (R-MT*K-MAX; MAX L IN WF, V-NMT
0.30 6 0 (GLOBAL E-PARAMETER WITH n OTHER CHOICES, global
APW/LAPW)
0 0.20 0.000 CONT 0
0 -6.50 0.005 STOP 0
1 0.40 0.000 CONT 0
1 -3.97 0.005 STOP 0
2 0.40 0.010 CONT 1
2 1.50 0.000 CONT 1
K-VECTORS FROM UNIT:4 -8.0 2.5 emin/emax window
The mixing factor is 0.1 and 5000 k-points in the whole Brillouin zone.
Then I run a spin-polarized execution and a FSM calculation with m=0.1
with energy convergence set to 0.00001.
All these options above are exactly the same that I choose when
executing the calculation in the old version of Wien2k (Wien2k_03) and
everything was right. But now, with the latest version the converged
value of the total magnetic moment is m=0.49.
On the other hand, when I look at the alternating charges as you
suggested me the diffrence between them is the wrong value m=0.49 while
in the old version calculation the same difference was the right value
m=0.1.
I am really puzzled. Please tell me if you need further information
and/or the submission of any file that could be helpful to you.
Regards,
