[Wien] Unable to obtain plasma frequency despite GAP =0.

[Pranjal Nandi]

Dear Community,

Version 23.2

I am doing calculations with init_lapw prec 1 - sp and kgen 1000. In the SCF file I clearly see GAP = 0 (I have shared a part of scf below).

Hence, I expect to get a plasma frequency if I change the switch to 6 and run x joint.

However, I am not getting any plasma frequency.  It would be helpful if you could please help.

I have increased the following.

In1c - K-VECTORS FROM UNIT:4   -9.0       15   161   emin / de (emax=Ef+de) / nband
Inop - -5.0 20.0 9999 Emin, Emax for matrix elements, NBvalMAX

Part of scf output.
:GAP (this spin):  0.200925 Ry =     2.734 eV (accurate value if proper k-mesh)
:GAP (global)   :    0.0    Ry =     0.0   eV (metal)
:GAP (this spin):    0.0    Ry =     0.0   eV (metal)


Looking forward to your kind suggestions.

With warm regards,
Pranjal
