Time dependent laminar flow past circular cylinder

Hi,
I am trying to solve time-dependent laminar flow past a long circular cylinder at Re=100 in unconfined condition. I am using rectangle domain.
The boundary conditions employed for inlet is the inlet bc with uniform velocity and at the outlet I imposed the pressure, no viscous stress.
I have a question about remaining two boundaries...
What should we can use for those two boundaries?
I tried with slip boundary but I didn't get vortex shedding even at Re=100.
Can anybody guide me for this problem??
I will be really thankful for it.

Please can you make it more clear?

Symmetry boundary condition. That would be equivalent to simulating an infinite array of cylinders: no flux lines would be allowed to penetrate the symmetry boundary.

Now it works... Thanks Daniel
