Operators and Functions

Operators

You can add an operator to a feature, property, or component.

To add an Average, Integration, Maximum, or Minimum operator:

1	Under the Building Blocks branch click Components.

2	On the Home toolbar, from the Building Blocks group, click Component ().

3	Right-click the Component node and choose Average, Integration, Maximum, or Minimum from the Operators submenu.

Defining an operation is similar to the way it works in the Model Builder but with a few differences.

•	The Operator name follows the same rules as variables; see Entering Names. You usually have to use feature scope for any operation defined by a feature, otherwise you get a duplicate definition if you have more than one feature of that type.

•	The Show in plot menu check box is selected by default. Clear that check box to remove the operator from the plot menus in results and probe features.

•	For the Selection section, in the Physics Builder you cannot specify absolute selections as you can in the Model Builder. See Specifying Selections for more information.

The Average, Integration, Maximum, and Minimum component couplings are supported as operations in the Physics Builder. The Integration Over Extra Dimension operator is also available.
