Please review the "Laminar Pipe Flow" tutorial to understand how to rotate, zoom-in and zoom-out the geometry in the Graphics Window.

Define Solver Properties

In this section the various solver properties will be specified in order to obtain the proper solution. On the left side of the window (Click) Problem Setup> General. Make sure that Pressure-Based is selected under Type and Transient is selected under Time in the Solver section. Note: LES is a transient simulation where the solution is marched in time.

Next, the Viscous Model parameters will be specified. In order to open the Viscous Model Options (Click) Problem Setup > Models > Viscous - Laminar > Edit.... Click Large Eddy Simulation under Model and WMLES under Subgrid-Scale Model. Click OK.

An Information box will appear, click OK. Basically, FLUENT switches the discretization scheme for momentum equation to Bounded Central-Differencing. It also urges to change the order to Second Order  in the Solution Methods which we will do in the later stages.
