Start the analysis by clicking on the 
(Run) button in the toolbar. The Residuals display will automatically be created and will show the solver's progress. For this case, however, the Area Averaged Inlet Pressure Plot is a more useful plot to view during the run. The tabs at the top of the Graphics window make it possible to select any active display for viewing.
During the run, it is possible to stop the solution by clicking the 
(Stop) button in the toolbar. If you do halt the simulation, it can be continued again by clicking on the (Run) button. If left alone, the simulation will continue until 600 iterations are completed.
The Area Averaged Inlet Pressure Plot at the end of the calculation should look as shown below.
Note that the pressure at the inlet has almost converged to a steady value. However, it is unlikely to do so completely as the solution to this problem is not truly steady-state.
