The case.clmsum_sofile is just a temporary file created by initso_lapw
from the normal (non-so) case.clmsum. (because in spin-polarized
calculations symmetry could be reduced by so and some atomic positions
could split into non-equivalent sites. Thus case.clmsup/up/dn files need
to be modified to account for the additional non-equivalent atoms and
this is stored temporarely in clmsum_so.
In WIEN2k it is ALWAYS case.clmsum which contains the density of an
scf cycle, both, with or without spin-orbit.

Dear Wien2k authors and users
I‘m interested to study the topology of electron charge density of these
cases using the critic2 code. To calculate the electronic structures, I
used the wien2k13.1 using the B3PW91 with alpha=0.2 and PBE-GGA
exchange-correlation functionals. The spin polarization and spin-orbit
coupling (SOC) have been considered in these calculations. After
convergence the charge and stopping scf calculations, I compared the
case.clmsum file generated within PBE-GGA with that of generated
within B3PW91. They are very different.
However, the case.clmsum_so file within PBE-GGA is the same as that of
B3PW91:
[yazdani@cm3 diff]$ diff case.clmsum_so-B3PW91 case.clmsum_so-GGA
[yazdani@cm3 diff]$
Could you help me to know that why the case.clmsum_so files of GGA and
B3PW91 are similar while this is not the case for case.clmsum?
What is the difference of case.clmsum and case.clmsum_so?
Does Wien2k update the case.clmsum_so during the scf calculations?
If yes, why is the case.clmsum_so generated by GGA is the same as that
of B2PW91?
If No, what is the role of case.clmsum_so in the claculations?
Does Wien2k consider the SOC effects in generating the case.clmsum file?
Which file must be used for critic2 code if SOC is considered?
case.clmsum or case.clmsum_so?
Thanks for your helps
Sincerely Yours
Majid
