Animate | Compare Shapes Menu

This menu is enabled during shape comparison animation.

Compare Shapes | Flip Right Sign

Multiplies the right hand (comparison shape) by "-1" during Comparison Animation.

• If two similar shapes appear to be animating 180 degrees out of phase with one another, the phases of one shape can be changed by 180 degrees so that the two shapes animate more closely together.

Flipping the Sign In a Complexity Plot (VES-4000 Modal Analysis option)

If two Animation Sources contain complex shapes, flipping the sign of the right-side comparison shape may not align them.  The Complexity Plot gives more control over the signs of shapes from an Animation Source.

During Comparison animation,

• Execute Display | Complexity Plot in the Animation Source Any Data Block, Shape Table, or Acquisition window that is open in the Work Area is an Animation Source. The currently connected Animation Source is displayed in the Animation Source list on the Toolbar in the Structure window. During animation, data from each M# in the current Animation Source is animated using the Animation equations for each Point on the structure model. window to open its Complexity Plot.

• Execute Display | Shape Normalized in the Complexity Plot window.

• Rotate the normalization line on the Complexity Plot by clicking & dragging it to flip the phase of the normalized shape. (See Complexity Plot for details.)

Compare Shapes | Closest Frequency/Time

Displays two shapes that are closest in frequency (or time) to one another during Comparison animation.

• When the shape from one Animation Source is selected, the shape with the closest frequency (or time) in the other Animation Source is automatically selected and displayed.

• If one of the Animation Sources is a Data Block or Acquisition Window, the cursor will be move to the closest frequency (or time) to match the frequency in the other Source.

Compare Shapes | Maximum MAC (VES-4000 Modal Analysis option)

Displays two shapes with the maximum MAC value during Comparison animation.

• When the shape from one Animation Source is selected, the shape in the other Animation Source is automatically selected to maximize the MAC value between the two shapes.

• If one of the Animation Sources is a Data Block or Acquisition Window, the cursor is moved to the closest frequency (or time) to maximize the MAC value between the two shapes.

Compare Shapes | Shape Difference

If checked, the right hand (comparison shape) is replaced with the difference between the right and left shapes during Comparison animation.

NOTE:  When this command is checked, the Animate | Amplitude commands only change the amplitude of the Shape Difference on the right hand (comparison shape)

Compare Shapes | Scale Relative To Left Shape

If checked during Comparison animation, the right-hand (comparison) shape is scaled relative to the left-hand (baseline) shape.
