periodic boundary condition in fluent

i want model a supersonic intake cone in fluent(3D), to reduce run time i want model only 10degree of it,how can active periodic boundary condition in fluent(ansys 14)?

Are you sure that the case is not axisymmetric?

For periodic boundaries, set the types of the two boundary faces to "interface" in the boundary conditions tab. Then you can set up a periodic interface.

thanks from your answer,
in 2d simulation i used axisymmetric i want this boundary condition to simulate 3d for 45degree of a revolve sketch.
