Choosing a Variable to Optimize

Before optimizing a variable, you must specify that you intend to use it during an optimization analysis in the Properties dialog box.

1. To choose a variable to optimize:
   1. If the variable is a design variable, click Twin Builder > Design Properties. You can also access the design variables from a menu in the lower left corner of the following Optimization dialog boxes: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and DesignXplorer Setup. Click Edit Variables > Edit Design Variables.
   2. If the variable is a project variable, click Project > Project Variables. You can also access the project variables from a menu in the lower left corner of the following Optimization dialog boxes: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and DesignXplorer Setup. Click Edit Variables  > Edit Project Variables.

   The Properties dialog box appears.

2. Click the tab that lists the variable you want to optimize.
3. Click the row containing the variable you want to optimize.
   Note:

   Dependent variables cannot be optimized.

4. Select Optimization/Design of Experiments.
5. For the variable you want to optimize, select Include.

The selected variable will now be available for optimization in an Optimetrics setup defined in the current design or project.

Note:

Complex numbers are not allowed for variables to be used in an Optimetrics sweep, or for optimization, statistical, sensitivity or tuning setups.

6. Optionally, override the default minimum and maximum values that Optimetrics will use for the variable in every optimization analysis. During optimization, the optimizer will not consider variable values that lie outside of this range.
