Solving Boundary Conditions in 2D Axisymmetrical Model

[Giorgia]

Hi! I can't understand how to implement boundary conditions in a 2D axisymmetrical model. How should be the value of pressure, x-velocity and y-velocity at the axis of symmetry?

Thank you!

You will have to give more details. You don't even mention which physical system you are talking about.
