    - Manipulating Regions and Boundaries
      Combine the separate mesh blocks into a single contiguous mesh, then rename the mesh entities before continuing with the simulation.
    - Setting Up the Physics Models
      Models define the primary variables of the simulation, including pressure, temperature and velocity, and what mathematical formulation is used to generate the solution.
    - Setting Fluid Properties
      Since the Ideal Gas model has been chosen, the viscosity, specific heat, and thermal conductivity fluid properties must be set.
    - Setting Boundary Conditions
      In this simulation, the freestream Mach number is 0.21, the freestream pressure is 98,258.18 Pa, and the freestream temperature is 300 K. Use the default reference pressure of 101,325 Pa, which means that the freestream gauge pressure is -3066.82 Pa.
    - Setting Initial Conditions
      In compressible fluid problems, it is advisable to initialize the flow to a non-zero initial velocity and a meaningful pressure. Here, you use the freestream velocity and the duct outlet pressure.
    - Adding Field Functions
      Field functions provide a mechanism by which fields (raw data from the simulation stored in cells and/or on boundaries) may be viewed and defined.
    - Setting Stopping Criteria
      Stopping criteria allow you to specify the length of the simulation, in this case the number of iterations to be performed.

Running the Simulation

Run the simuation and examine the Residuals display.

To run the simulation, click the (Run) button in the toolbar.
If you do not see this button, use the Solution > Run menu item. You could also show the Solution toolbar by selecting Window > Toolbars > Solution, and then clicking the toolbar button.

The Residuals display is created automatically and shows the progress of the solver. If necessary, click the Residuals tab to bring the Residuals plot into view.

During the run, it is possible to stop the process by clicking the (Stop) button on the toolbar. If you do halt the simulation, it can be continued later by clicking the (Run) button. If left alone, the simulation continues until the stopping criterion of 200 iterations is satisfied.

Save the simulation after the run has finished.
