Dear all,<br>
<br>
I have been trying to perform U+SO comptations on Sr2RhO4 to get a
bandstructure.<br>
<br>
My scheme is the following:<br>
<br>
Initialize spin-polarized case<br>
init_orb_lapw -orb<br>
init_so_lapw<br>
runsp_lapw -orb -so<br>
define case.klist_band<br>
lapw1 -up -band -orb<br>
lapw1 -dn -band -orb<br>
put Fermi energy in case.scf<br>
spaghetti -up -so<br>
<br>
This works well for instance for ZnO, which does not have an
inversion symmetry (and so initialize a case.in1c file - see below).
<br>
For Sr2RhO4 (group 142, inversion present), symmetso in
"init_so_lapw" step will not detect symmetries others than group A
or B, and so proposes no change for the group (I assume I can keep
the old case.struct file when asked, but the other option makes no
difference for the error).<br>
<br>
However, step lapw1 will stop, looking for case.inc1 file, that is
as for a case with no inversion symmetry (and this file is indeed
not present at this step). Probably some basic misunderstanding, but
this seems to be in contradiction with the case group symmetry after
symmetso ?<br>
<br>
Thanks for help<br>
