Laminar Jet Setup 

Display the mesh by selecting and displaying the appropriate surfaces (fluid) in the General-Mesh-Display dialogue below.

Make sure that the axisymmetric solution is selected under 'General', viscous-laminar is selected under 'Models', and that the appropriate boundary conditions and materials for the laminar case were selected based on the Problem Specification. 

Initialize the solution by going to 'Solution Initialization' and using Inlet 1 with axial velocity 1m/s to initialize the domain. Check your initialization by going to  Results-Graphics and Animations and displaying the stream function (constant values along streamlines, which are tangent to flow velocity)  for the fluid surface as in the dialogue box below. 

Your initial velocity stream function should look like this:

Laminar Jet Solution

Now obtain a converged solution by running the solution for 1000 iterations in 'Run Calculation'. Your solution should be reasonably converged upon examining the x, y, and continuity residual plots:
