[Wien] regarding plasma frequency of semi conductor and insulator

[yasir saeed]

Hi Prof. Blaha and wien user
I am using Wien2k 10 and calculating optical properties.
I calculate the TiC optic with 72 kpoint (just for checking) and than change 
switch to 6 in TiC.injoint and find plasma frequency in TiC.outputjoint =2.97
But when I do same for Si with 72kpoint , its gives 0.000 plasma frequency.
how I find the plasma frequency for Si.
any response in important for me.
thanks in advance
