define pressure boundary condition

Hi all,
I am trying to simulate the cylinder flow problem using the streamfunction-vorticity form in PDE form and coupling the pressure term into the system by the pressure Poisson equation to compute the pressure field in order to calculate the stress on the cylinder.
the first step is ok and i can get the good results for the velocity field in both steady and transient state but failed to solve the presure poisson equation as i can't find a proper way to define the correct pressure boundary conditions for it.
Is anyone can help me to do that?
Thanks!!!!

The pressure boundary conditions need to be defined including the inflow,outflow,cylinder surface and the solid walls.
Thanks
Thanks
