Modifying the Value of a Fixed Variable

If you are not including a variable in an optimization, sensitivity, or statistical analysis, Optimetrics uses that variable's current value during the analysis.

To override the current value of a fixed variable for an Optimetrics setup:

1. Do one of the following:

• In the Setup Optimization dialog box, click the Variables tab.
• In the Setup Sensitivity Analysis dialog box, click the Variables tab.
• In the Setup Statistical Analysis dialog box, click the Variables tab.

2. Click Set Fixed Variables to open the Setup Fixed Variables dialog box. Under Fixed Variables, all of the current independent variable values appear.

3. Click the Value text box of the variable with the value you want to override.
4. Type a new value in the Value text box and press Enter.

The Override option is now selected. This indicates that the value you entered is used for this Optimetrics setup; the current variable value set for the nominal design is ignored.

5. Optionally, click a new unit system in the Units text box.
6. Click OK.

To revert to a default variable value, clear the Override option.
