Functions

You can add a Function to a feature, property, or component. The function names follow the same rules as variables; see Entering Names. You usually have to use feature scope for any function defined by a feature, otherwise you get a duplicate definition if you have more than one feature of that type. Apart from the name syntax, defining a function works in exactly the same way as in the Model Builder.

The following functions are available: Analytic, Gaussian Pulse, Image, Interpolation, Piecewise, Ramp, Random, Rectangle, Step, Triangle, Waveform, and Tensor-Valued Function.

To add one of the available functions:

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 a function from the Functions submenu.

In the function node’s Settings windows (except for Tensor-Valued Function), 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.
