Default Navier-Stokes with slip Boundary conditions

I am working in my PHD developing a method to solve the incompressible Navier-Stokes equations. This methodology solve the velocity using a system for each component (decoupled system) and then pressure is corrected. Now I have found problems trying to impose slip boundary conditions. I don't know how to carry this out using the decoupled system. Has anyone an idea to solve this problem?

You need to give a more complete description of your solver in order for anyone to help...

I can give you my Code. But what you will do for me? Better ask Prof. Peric or do "google" search for "peric.tar.gz" you will get it.

I think Neumenn B.C.on slip boundry should help. But as Bamoi said, you have to give more details.

(1). The only decoupled formulation for incompressible Navier-Stokes equations is in terms of three velocity component equations and three vorticity component equation. (2). There, the pressure is always decoupled and does not involved in the calculation of the flow field (velocity). The pressure can be derived from the momentum equation or pressure equation once the velocity field is obtained. (3). If you need to solve the pressure equation, then, it is really not decoupled formulation. The pressure-based formulation is really not decoupled formulation, because when you solve the momentum equation, you still need the information from the pressure field. So, it seems to me that you are dealing with pressure-based formulation rather than the decoupled-velocity-vorticity formulation. (4). The velocity-vorticity formulation is fairly standard, and you should be able to find the related information from cfd books or technical papers.
