Dear
wien2k users and developers

I
want to calculate Zn K-edge ELNES of the bulk wurtzite ZnO. For
calculating the ELNES of bulk without core-hole approximation, I have
no problem. The scf run succesfully as well as ELNES.
for
core-hole, I set in the structure:

spacegroup=156
(P3m1)
Zn1
1/3 2/3 0       RMT=2.2
Zn 2/3 1/3 0.5     RMT=2.2
O 1/3 2/3 0.383    RMT=1.3
O 2/3 1/3 0.883    RMT=1.3
---------------------------------------
I
labled one of the Zn atoms to 1, for core-hole calc. spacegroup
changes from 186(p63mc) to 156 (p3m1)
---------------------------------------

When
I want to use corehole approximation (for Zn 1s ELNES) in the bulk of
wurtzite ZnO, the L2main - QTL-B Error appears. All recommendations
about the solve of this error listed in mailing list and FAQ could
not solve this error in my case!!! such as reducing the mixing
factor, removing the local orbital in zno.in1c, or using the switch
-in1new.

I
listed zno.scf2 and zno.scf1 in below:

zno.scf2:
================================

QTL-B
VALUE .EQ.   62.71953 in Band of energy  -0.42747  ATOM=    1  L=  0
Check
for ghostbands or EIGENVALUES BELOW XX messages
Adjust
your Energy-parameters for this ATOM and L (or use -in1new switch),
check RMTs  !!!


:WARN

================================


by
attention to the WIEN2k-FAQ: QTL-B page, seems that error is
concerned to the Zn 1s orbital (Atom 1  L 0) that I want to calculate
its ELNES!!

Please
help me for this error
Thanks
