Types of Animation

  • Linear Animation

    It starts with original position of structure and ends with deformed position of structure. Number of frames provided by user are linearly interpolated between initial and deformed positions.

     

  • Transient Animation

    This is to animate the structure with time step positions computed by a solver. It extracts all instances into frames. User is not allowed to change number of frames.

    Each frame refers to one instance or one time step.

     

  • Animation of Results

    This is to animate the frames in which each frame refers to a result. User is not allowed to change number of frames.

     

  • Eigenvector Animation

    Animating eigenvector results (complex eigen as well as mode case data).

     

  • Dataset Animation

    This is to animate all data sets. Each frame in this option is a dataset. The CAE result for each dataset will be either a default one or user chosen one.

VCollab supports harmonic motion and swing motion in addition.

 

CAE Animation

CAE Animation is  computing and simulating of CAE data with finite number of frames from original to displaced one.

For example, Let CAE data have 4 frames for animation.

Animation of this data is to display frames 1, 2, 3, 4 sequentially and cyclically.

Animation starts with  frame 1 and ends with frame 4.

 

Swing Motion

To display the frames 1,2,3,4,3,2,1 sequentially and cyclically. Animation starts and ends with initial frame.

 

Harmonic Motion

To compute equivalent mirror frames of all these 4 frames and displaying frames -4,-3,-2,-1,1,2,3,4 sequentially and cyclically. This motion is applicable for static analysis only (i.e., Linear Animation).

 

Harmonic with swing motion

To display frames -4,-3,-2,-1, 1,2,3, 4, 3,2,1, -1,-2,-3,-4 sequentially and cyclically.

This type of motion is applicable only for Linear Animation.

Synchronize

This option is enabled if two or more dataset exist. This synchronizes similar animation types of all datasets.

Capture Animation

This option helps user to save one complete cycle of animation into either into a movie or a set of user specified image formats.

Scale Factor

This option is a link to CAE Scale factor settings dialog.

RAM / HDD

User has two option to store animation frame data either into RAM and HDD.

  • RAM - this option provides an improved performance during animation. This performance will reduce and hang if RAM free space is less or nearly null.

  • HDD - this option stores frame data into hard disk and revoke it whenever necessary. If memory is nearly full in RAM, user can use this option for a better improved cycle.

Note:

Any change in animation settings is applicable for current dataset only, if more than one model exists.

 

How to play Linear Animation?

  • Click  CAE | Animation Settings
  • Select Animation type as Linear in the popped up dialog.
  • Provide number of frames.
  • Click Harmonic and Swing motions if necessary.
  • Click Apply and Animate.

How to play Transient Animation?

  • Click  CAE | Animation Settings
  • Select Animation type as Transient in the popped up dialog. All instances are selected by default.
  • Select Number of instances if necessary.
  • Select Swing motion if necessary.
  • Click Apply and Animate.

How to activate Mode Case animation or Eigen Vector Animation?

  • Load CAX file.
  • Click 'CAE | Animation Settings'
  • For mode case and complex eigen data, default animation will be Eigen Vector animation.
  • If not, select 'Eigen Vector' option.
  • Click Apply and Animate buttons to activate animation.

How to improve performance during transient animation?

  • Click Animation Settings which pops up animation controls dialog.
  • Select or Check 'Prepare & Play' option.

  • It prepares animation frames for better performance.
  • It is very useful for large data set.

 

How to play CAE results Animation?

  • Click  CAE | Animation Settings
  • Select Animation type as Results in the popped up dialog. All results are selected by default.
  • Select the results for animation if necessary.
  • Select Swing motion if necessary.
  • Click Apply and Animate.
How to play Dataset Animation?
  • Load a CAX file.
  • Merge more CAX files.
  • Click 'CAE | Animation Settings'.
  • Select 'Dataset' as type of animation.
  • Click 'Animate' to animate all the datasets available.
  • Below is the sample animation for datasets, in which each frame refers to a dataset.

How to capture animation into a movie?

  • Click 'Capture Animation' button in settings panel.
  • It pops up 'Capture CAE Animation' dialog.

  • Click file browser button.
  • Select any 'Save as type' from the list of .mp4, .flv, .wmv, .gif, .avi, .jpg, .bmp, .tif, and .png.
  • Click 'Capture' button.
  • Wait for confirmation message.

  • Click 'OK' to complete the process.

Note:
If output file type is of image, all frames will be saved as image files.

What is the advantage of 'Skip By' option?

If the CAE animation cycle contains a huge number of frames, user may fed up with time taken for a cycle. This option helps user to reduce the cycle time, but view a better and complete simulation by skipping odd frames or two or more frames.

  • Consider the following image, which contains 201 frames.

  • It will consume more than one minute, if the time interval between frames is 0.5 seconds.
  • Number of frames can be reduced to 101 by skipping alternative frames.

  • Further it can be reduced to 67 frames by skipping two frames as below.

 

How to animate model relative to a position or point or node?

  • Click 'Pivot...' option in CAE Animation Settings dialog.

 

 

 

 

 

 

 

 

 

 

 

  • It pops up 'Pivot Settings' dialog.

  • Select 'Node' in the Pivot combo box.

  • Click 'Pick' button to select the node in the model.
  • Click a node on the model.

  • Node number is displayed in the ID text. i.e., Picked ID will be considered as Pivot point.
  • The deformation at the pivot point is fixed.
  • Now animate the model and notice that simulation changed relatively to pivot point.
