optics with VASP

[chandrima]

Hi
I am trying to compute the dielectric function in VASP using LOPTICS = . True.
In order to use this option do I need to provide a pre-generated KPOINTS file with explicit k-point and tetrahedron lists ?
Does VASP 5.2 support automatic k-mesh generation for computing the dielectric function ?

Thanks a lot.

This is a question for the main vasp forum. We only deal with the transition state finding code here.
