Double click on Setup which will bring up the FLUENT Launcher. Click OK to select the default options in the FLUENT Launcher. Twiddle your thumbs a bit while the FLUENT interface comes up. This is where we'll specify the governing equations and boundary conditions for our boundary-value problem. In the left-hand side of the FLUENT interface, we see various items listed under Problem Setup. We will work from top to bottom of the Problem Setup items to setup the physics of our problem. On the right hand side, we have the Graphics pane and, below that, the Command pane.

Display Mesh

 LetLet's first display the mesh that has been was created in the previous step. 

Problem Setup > General > Mesh > Display...

 
The long, skinny rectangle displayed in the graphics window corresponds to our solution domain. Some of the operations available in the graphics window to interrogate the geometry and mesh are:

Translation: The model can be translated in any direction by holding down the Left Mouse Button and then moving the mouse in the desired direction.

Zoom In: Hold down the Middle Mouse Button and drag a box from the Upper Left Hand Corner to the Lower Right Hand Corner over the area you want to zoom in on.

Zoom Out: Hold down the Middle Mouse Button and drag a box anywhere from the Lower Right Hand Corner to the Upper Left Hand Corner.

Use these operations to zoom in and interrogate our mesh.

You should have all the surfaces shown here.  You should check whether each surfaces correspond to the right geometry by unchecking unrelated surfaces and click Display to view the surface of interest in the Graphics window.

Next, we will specify that the problem we are solving is axisymmetric.
General > Solver > 2D Space > Axisymmetric

 
Now let's move on to setting up our model. We will first turn on the energy equation.
Models > Energy - Off > Edit...
Turn on the Energy Equation and click OK.
 
Next, we will setup the Viscous model.
