Animate and Record Results

If you've previously run a 3D printing analysis, use the Animation toolbar to animate and record the results.

Prerequisite: Run a 3D printing analysis.
  1. Select the Show Analysis Results tool on the Analyze icon.

    The Animation Toolbar appears at the bottom of the modeling window.

  2. Review the animation.
    • Click the button on the Animation toolbar to review the analysis. Click the button to pause the animation.
    • Drag the slider on the animation toolbar to view a particular point during the printing analysis.
    • Click the icon to change the animation settings.
  3. Record the animation.
    • Click the button on the animation toolbar to begin recording the motion results; the icon changes to red to indicate that it is recording. Click the icon again to stop recording.
    • When a recording is finished, the video is automatically saved in the C:\Users\username\Documents\Altair\captures directory. It is automatically given a name constructed from the time stamp, i.e. recording2018.8.8_15.47.39.mp4.
  • The default behavior is continuous recording, but the recording will stop automatically if the playback option is set to Once rather than Loop.
  • To hide the workflow help, select File > Preferences, and in the Workspace category clear the Show workflow help check box.
  • To avoid recording the mouse cursor, click the button on the animation toolbar and press the Tab key to move the focus to the button. Then press the Spacebar to start or stop the recording.
  • Note that the video recorder captures everything in the region of the modeling window. Avoid obscuring or minimizing that window during the recording process.

Animation Toolbar

Use the animation toolbar to play, record, and configure the animation.

Animation Settings
Click to open the Animation Settings.
Play and Record/Stop Recording
Click the button to begin recording the results; the icon changes to red to indicate that it is recording. Click the icon again to stop recording.
Start Animation/Pause Animation
Click the button to start or pause the animation. Use the arrow buttons to jump the first or last frame in the animation.
Move to First/Previous/Next/Last Step
These buttons allow you to step through the animation frame-by-frame. If you hold down the Previous or Next button, it will auto-repeat. If you want to skip frames, use the Increment By feature in the Animation Settings; hold Ctrl to temporarily override this behavior.
Drag the slider on the toolbar to view a particular point during the analysis; use the arrow keys to move frame-by-frame through the animation.
Current Step
Displays the current time or frame. You can also enter a value to go to the nearest time/frame.
Connection Results (structures only)
Click to extract reaction forces at fasteners. This option is only avaiable for structural analysis.
Make Current Frame the New Design Position (motion analysis only)
Click to use the current position of the mechanism as the model's starting point for the next run. This option is only avaiable for motion analysis.
Plot Manager (motion analysis only)
Open the Plot Manager to browse and plot motion results data, create cross plots (data vs. data), define pages in different layouts, and save the plots you've defined as a template for reuse. This option is only avaiable for motion analysis.
Display Linear Modes Table (motion linear analysis only)
Open the Linear Modes table to view the results of a linear analysis in complex number form with natural frequencies and damping ratio. This option is only avaiable for linear motion analysis.
Note: The animation toolbar has Previous and Next buttons with an auto-repeat feature, allowing you to step through the animation frame-by-frame by holding down the button. In addition, the Animation Settings include an option to Reverse Playback.

Animation Settings

Modify the animation settings from the animation toolbar.

Figure 2. Animation Settings
Select whether to play the animation on a continuous Loop, Once, or Bounce (between forwards and backwards). Select the check box to Reverse Playback.
Set the units for the slider to either Time or Frame.
Increment By
Increase the value in the counter to skip frames during playback. The reset button restores the default value of 1.
Drag the slider to change the speed of the animation.
Select the Range checkbox to define and starting and ending frame for the animation. This allows you to limit the playback range to just a portion of the animation, making it easier to study behaviors in more detail. You can use the Ctrl key while clicking on the Start or End icons to jump to Range Start and Range End, respectively.
Note: For motion models, you can fit plots for the selected range by using the Ctrl key while double-clicking. Also, the paths of tracers will be trimmed to honor the specified range.
Scale Factor
Enter a custom value to change the scale of the animation. Generally the scale of a displacement is too small to see clearly, so auto scaling is enabled by default.
Recording Settings
The default Auto setting gives you an estimate of the duration of the recording at 30 frames per second. If your video plays back faster than you want, select Custom Duration to change the length of the video; this will adjust the frame rate to try to achieve the specified duration. The Custom Duration has a minimum value of 1 second, and maximum value of 30 seconds.

Animation Shortcuts

To Do this
Play and pause If the Play button is active, press the Spacebar.
Go to the first/last frame Press the Home or End key.
Go to the next/previous frame Press the Page Up or Page Down key.
Increment the slider

Use the arrow keys to move frame-by-frame through the animation, or position the cursor over the slider and use the scroll wheel.

Exit tool Right-click and mouse through the check mark to exit, or double-right-click.
