# Animation Settings

The Animation Settings dialog box allows the parameters that govern animation to be specified.

Open this dialog box by giving the “Graphics | Display | Settings | Animation Settings” menu command. This dialog box may also be opened from the Graphic Settings dialog box.

(Animation may be switched on by giving the “Graphics | Display | Animate” menu command or from the Orientation toolbar.)

# Definition

Period of animation

Specifies the approximate time to be taken to animate from the undeformed position through to maximum deformation and back to undeformed. Mode shapes are animated from positive deformation to negative deformation; in this case the period is for a half animation cycle.

When animation is by stepping through the cases in the cases list the period of animation specifies the approximate time to step through all of the cases.

When Override with modal period if animating mode shape is checked and a mode shape is being animated the period of animation is automatically set to the modal period and the specified value is ignored. However the specified period of animation is used if ( 0.1s < modal period < 60s ).

Animate diagrams and contours with deformation

When checked the scales of diagrams and contours are reduced with the deformation.

This assumes a linear relationship between diagram / contour data and deformation, which may not be appropriate. This feature is only offered for visualisation purposes.

Rotation, Period of complete rotation about model

Specifies the approximate time to be taken to rotate the model through 360°. Rotation only occurs when “Do rotate when animating” is set.

Rotation mode

Don’t rotate – The model is not rotated.
Do rotate – The model is rotated about the object point when animated.
Rotate if undeformed – The model is rotated about the object point when animated if the image is undeformed. No rotation occurs if the image is deformed.
