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, click Maxwell 3D (or Maxwell 2D, or RMxprt) > Design Properties. You can also access the Design variables from a menu in the lower left corner of the following Optimization dialogs: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and Design Xplorer Setup.

    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 dialogs: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and Design Xplorer Setup.

  2. Click Edit Variables and from the menu select Edit Design (or Project) Variables.

    3. The Properties window appears.

  3. Click the tab that lists the variable you want to include in the sensitivity analysis.
  4. Click the row containing the variable you want to include in the sensitivity analysis.
    Note: Dependent variables cannot be included in a sensitivity analysis.
  5. Select the Sensitivity option.
  6. For the variable you want to include in the sensitivity analysis, select Include.

    7. The selected variable is now available for sensitivity analysis in a sensitivity setup defined in the current design or project.

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

  7. Optionally, override the default minimum and maximum values that Optimetrics uses for the variable in every sensitivity analysis. During sensitivity analysis, Optimetrics does not consider variable values that lie outside of this range.
  8. Optionally, override the default initial displacement value that Optimetrics uses 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.
  9. Click OK.
