Default axisymmetric nozzle

I try to simulate supersoni flow from axisymmetric nozzle. So, what should I do, apply symmetry boundary condition or make a periodical interface with 1:1 connection?

Either will work, but a periodic interface will allow swirl and may not converge quite as smoothly.

Thank you. I am going to solve with symmetry boundary condition firstly.
