Deformation Scale Factor

Deformation scale factor (or amplitude modulation) consists in scaling the maximum displacement amplitude for visualizing a deformed mesh image.

You can either choose a large scaling coefficient to zoom on the deformed geometry or a small coefficient to obtain a realistic visualization.

This task shows how to use the Amplitude Modulation capability.

You can use the sample26.CATAnalysis document: you created a Stress Von Mises image.

Before You Begin:

	Go to `View -> Render Style -> Customize View` and make sure the `Edges points` option is not active and the `Materials` option is active in the Custom View Modes dialog box.
	Activate the `Von Mises Stress (nodal value)` image by right-clicking on this feature in the specification tree and selecting the `Activate/Deactivate` option from the displayed contextual menu.

1. Click the Deformation Scale Factor icon in the bottom toolbar.
The Deformation Scale Factor dialog box is displayed.

The deformed geometry is visualized with the default values of the following parameters:

Magnification cursor: further allows you to dynamically change the scale factor from 0 to Max.

Scaling factor: Deformation coefficient. You can choose to use the Default Coefficient.

Maximum displacement: the value in mm of the maximum allowed displacement on the image.

You can edit the Deformation Scale Factor dialog box and set the parameters.

2. Enter 100mm as Maximum displacement new value in the Deform Window dialog box.
The Magnification cursor is automatically set to Max.

A new image is displayed with your settings taken into account.

3. Click OK to exit the Deformation Scale Factor dialog box.

The Amplitude Modulation capability is also available for Frequency and Buckling Solutions.
