Working with Variables
Including a Variable in a Sensitivity Analysis
Before a variable can be included in a sensitivity analysis, you must specify that you intend for it to be used during a sensitivity analysis in the Properties dialog box.
1. If the variable is a design variable, do the following: Click HFSS or HFSS-IE>Design Properties.
If the variable is a project variable, do the following: Click Project>Project Variables.
The Properties dialog box appears.
2. Click the tab that lists the variable you want to include in the sensitivity analysis.
3. Click the row containing the variable you want to include in the sensitivity analysis.
Note |
Dependent variables cannot be included in a sensitivity analysis. |
4. Select the Sensitivity option above.
5. 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. |
6. 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.
7. 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.
