Periodic boundary

Hi again! The problem that I have with the periodic boundary condition in cylindrical coordinates still exists.My solver seems to have a small arithmetic problem,because when the velocity is very small (1.E-4) at the boundary the velocity has opposite signs.But this problem is overcome when the velocity is higher than about 0.005, but the problem with the pressure correction exists,where the starting values are zeros.Any thoughts?Have anyone faced that before?
