I'm new to CFD and OpenFoam and I need some help in defining correct boundary conditions on my test case.

I'm testing a case where constant volumetric flow goes through a contraction. I have created a mesh which consists from inlet, contraction and outlet. I would like to know how to specify the outlet condition so I will correctly see how the fluid's velocity is increased in the contraction. My inlet is of fixed value type with uniform velocity (0.1 m/s). Should I use the same for my outlet?
