CST simulation with unit cell boundary condition

hi
i am interested in having a look at the cst mws simulation of any structure which is using unit cell boundary condition.
any comments, links or pdf file are welcome

Hi,
It is automatic setting for unit cell boundary condition. But you can set it, see more in helping.

Hi Shahid,
What is the significance of this unit cell ? What are you looking for.?

hi GVVIN
thanks for your reply. well i want to simulate EBG structure so i am not sure whether to use periodic boundary conditions or unit cell boundary conditions ?
because periodic boundary conditions also repeat the structure infinitely .
do you have any document related to unit cell or periodic boundary conditions applications
thanks
