The Residuals display will be created automatically and will show the progress being made by the solver. You may observe the run progress by selecting one of the tabs at the top of the Graphics window. The Scalar Scene 1 display after about 50 iterations is shown below.
During the run, it is possible to stop the analysis by clicking the 
(Stop) button in the toolbar. If you do halt the simulation, it can be continued again later by clicking the 
(Run) button. If left alone, the simulation will continue until 1000 iterations have been completed.
Once this stage is reached, check that the solution has converged by examining the lift and drag coefficient plots.
0.2 and 0.8, respectively, to zoom in on the relevant part of the graph.
Both monitors have reached constant values so it is reasonable to conclude that the solution has converged.
Save the simulation.
