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.

   The Setup Fixed Variables dialog box appears. Under Fixed Variables, all of the current independent variable values are listed.

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 then 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.

   Note:

   Alternatively, you can select the Override option first, and then type a new value in the Value text box.

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.
