Specifying Output Variables

You can define output variables to use calculated expressions of results as adaptive convergence goals and for reports. You can use output variables in the Expression Cache tab of the Solution Setup dialog and select them as Categories in the Reports dialog, as well as the Output Variables window. You can access the Output Variables window in several ways.

• Click HFSS or HFSS-IE>Results>Output Variables.

• In the Project tree, right-click on Results and select Output Variables from the short-cut menu.

• In the Solution Setup dialog, select the Expression Cache tab, click the Add... button to display the Add to expression cache dialog, and click the Output Variables button.

• Click the Output Variables button the Reports dialog.

The Output Variables window contains four sections:

• Output Variables section, where you can specify the name and expression for a new output variable. Existing variables appear in the list at the top of the window. Clicking the triangle in the Name bar inverts the sort order.

At top of the Output Variables window, you can use a checkbox to Validate output variable for selected context.

• Context section, where you specify the Report type, the Solution, and for appropriate report types, the Domain. Changing the Report type to Near Fields, or Far Fields causes a Geometry menu to appear. Selecting Emission tests require a digital signal. All selections affect the Functions listed.

• Expressionsection, where you can insert quantities into the Expression area of the Output Variables section.

• Function section, where you can insert completed expressions into the Expression area of the Output Variables section.
