8 Click Solve.
9 When the parametric solver has finished, select the Solve using a solver sequence
check box again.
10 Click OK to close the Solver Manager.
Postprocessing and Visualization
Follow these steps to reproduce the plot in Figure 3-13 on page 99.
1 From the Postprocessing menu, choose Global Variables Plot.
2 From the Predefined quantities list, select Frequency, brass and Frequency, steel.
3 Click the Add Selected Predefined Quantities button (marked >) to add these two
expressions to the Quantities to plot list on the right.
4 Click the Line Settings dialog box. Change the selection in the Line marker list to
Cycle and then click OK to close the Line Settings dialog box.
5 Click OK to close the Global Variables Plot dialog box and generate the plot.
6 Click the Edit Plot toolbar button in the figure window.
7 In the Edit Plot dialog box, edit plot title, axis labels, and legends to finish the plot.
8 When done, click OK.
RESTORING THE MODEL
To save the model’s MPH-file with the solution for the combined brass-steel design at
an operating temperature of 100° C instead of the dummy solution generated in the
previous step, follow these steps.
1 Optionally, clear the previous solution history by choosing Reset Model from the File
menu.
2 If you chose to reset the model, click the Initialize Mesh button on the Main toolbar
to re-create a mesh using the settings you specified earlier in the Free Mesh
Parameters dialog box.
3 Click the Solve button on the Main toolbar to solve the model using the solver
sequence. Note that the solver sequence overrides the current settings in the Solver
Parameters and Solver Manager dialog boxes.
When the solver finishes, the plot in the drawing area should resemble that in the
following figure.
