Defining Parameter Defaults at the Design Level

Adding a Parameter Default

To define a new parameter default at the design level:

1. Access Design Properties one of three ways:
   • Click HFSS > Design Properties.
   • Right-click the design name in the Project Tree and select Design Properties.
   • From a menu in the lower left corner of the following Optimization dialogs: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and Design Xplorer Setup. Click Edit Variables and from the menu select Edit Design Variables

   The Properties window for design variables appears.

   

2. Click Add....

   The Add Property window appears.

   

3. Enter information for the parameter default, as applicable:
   • Name – the name can contain alphanumeric characters and underscores (_). You cannot use any names already defined on the General tab.
   • Variable Type – select Variable to enter a value, or select Separator to provide a bolded name for a blank line.

     Your selection impacts which properties you can edit:

     Variable Type	Editable Properties
     Variable	Unit Type, Units, Value.
     Separator	Name. A separator variable provides a bolded name for a blank line to facilitate grouping variables in variable lists.

   • Unit Type – for Variables, use the drop-down menu to select a type from the list (for example, Charge, Density, Energy, ...).
   • Units – for Variables, use the drop-down menu to select a unit of measure.
   • Value – for Variables, enter a valid numeric quantity. Alternately, you can assign a variable to a parameter by typing a variable name or mathematical expression in place of a parameter value.
4. Click OK.

   The new variable appears in the list. You can sort local variables by clicking the Name column header. Clicking once sorts them in ascending order, noted by a triangle pointing up. Clicking against sorts in descending order, noted by a triangle pointing down. Clicking a third time sorts in original order, with no triangle.

5. If desired, use the check boxes to designate a variable as Read-only, Hidden, or Sweep.
   • Read-only – when selected, the variable's name, value, unit, and description cannot be modified.
   • Hidden – hidden variables do not appear in the Properties window unless Show Hidden is selected.
6. Click Apply to apply changes.
7. Click OK to exit the window.
