Running the Simulation

It is not necessary to initialize the simulation in this case because we are restarting the analysis from a previous solution. To display Scalar Scene 1:

Open the Scenes node, right-click on the Scalar Scene 1 node and then select Open

The pressure profile on the external surface of the dilution pipe will be displayed in the Graphics window.

Change the displayed scalar to Mass Fraction of Methane by right-clicking on the legend color scale in the Graphics window.

Remove the reflected half of the problem geometry from the display by selecting the Scalar 1 node and changing the Transform property to Identity.

Change the view by clicking on the

button in the title bar and selecting Look Down > -Z > Up +Y.

To run the simulation, click on the

(Run) button in the top toolbar.

The Residuals display will be created automatically and will show the progress being made by the solver. If necessary, click on the Residuals tab to bring the Residuals plot into view. The tabs at the top of the Graphics window make it possible to select any of the active displays for viewing.

During the run it is possible to stop the process by clicking on the (Stop) button in the toolbar. If you do halt the simulation, it can be continued later by clicking on the (Run) button. If left alone, the simulation will continue until it has ran for 2.0 s of physical time.

Click on the Scalar Scene 1 tab to watch the solution as it gets updated.

After the run has finished, use the Save As... option in the File menu to save the simulation under the name dilPipeUnsteady@2.00e+00.sim

This is necessary because the final result is not autosaved.
