k-point sampling

[dwh]

HELLO EVERYONE
k-point sampling in the basic settings for the calculation,what is its role, how can I set up and would you give me some specific regularity ? Thanks.

It is a parameter to determine which Fourier component should be sampled in order to obtain the self-consistent Hamiltonian for the system.

I would suggest reading a book like http://www.amazon.com/Introduction-Solid-Physics-Charles-Kittel/dp/047141526X for more background material.
