Dear Wien2K users
In order to obtain the orientation sensitive ELNES,
the UG (pg 126) recommends to
use a “full k-mesh”, i.e. run kgen with only the identity operation in
case.struct.
Following the completion of a SCF calculation with a "reduced" (within
the IBZ) k-mesh,
I tried the following :
(1) edit case.struct and deleted all symmetry operations except the unit
one, so the bottom of file looks like this :
1 NUMBER OF SYMMETRY OPERATIONS
1 0 0 0.00000000
0 1 0 0.00000000
0 0 1 0.00000000
1
(2) x kgen # to get the "full" k-mesh
(3) x lapw1 -d
(4) x lapw1 # to get the new Vtot
(5) x lapw2 -qtl
(6) x telnes2
BUT
as soon as step-4 was attempted I got the message: ROTDEF - Error.
What is it that I am missing in the above steps ?
Any help is appreciated.
Dimitris
