Including a Variable in a Sensitivity Analysis
Before including a variable in a sensitivity analysis, you must specify that you intend to use it during a sensitivity analysis in the Properties dialog box.
- To include a variable in a sensitivity analysis:
- If the variable is a design variable, click Twin Builder > Design Properties. 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 Design Variables.
- 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.
- Click the tab that lists the variable you want to include in the sensitivity analysis.
- Click the row containing the variable
you want to include in the sensitivity analysis.
Note:
Dependent variables cannot be included in a sensitivity analysis.
- Select the Sensitivity option above.
- For the variable you want to include in the sensitivity analysis, select Include.
The selected variable will now be available for sensitivity analysis in a sensitivity 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.
- Optionally, override the default minimum and maximum values that Optimetrics will use for the variable in every sensitivity analysis. During sensitivity analysis, Optimetrics will not consider variable values that lie outside of this range.
- Optionally, override the default initial displacement value that Optimetrics will use for the variable in every sensitivity analysis. During sensitivity analysis, Optimetrics will not consider a variable value for the first design variation that is greater than this step size away from the starting variable value.
