CAE | Scale Factor

This command helps user to scale deformation of the model so that the deformation is visible and understandable by user.

 

Sometimes, User might be confused in understanding deformation, when deformation value of a node is,

  • Very large compared to other nodes, so that user could not identify what collapsed the model

  • Very small, so that user could not identify much difference in the deformation of model.

This option helps to understand both cases.

Note:

Any change in scale factor will affect selected dataset only, if more models are merged.

 

 

Scale Factor Panel

 

 

 

 

Uniform

User value will be applied to all X, Y and Z direction. This option is unchecked by default.

X, Y Z Allows user to enter scale factor for each direction.
Apply The modified scale factors will be applied on model and visible in viewer.

 

Max. Normalization for Mode Case Data

Panel displays additional interface for mode case data as below,

 

 

For mode case data, deformation is normalized (uniform -max - normalization) and mapped with model bounding box size.

By default normalized deformation is scaled to 10 percent of bounding box size for mode case data and 1 percent for Complex eigen data.

User can vary the value between 1 to 100.

To apply "True scale" uncheck  Normalize option and set scale factor  in 'Uniform' option as 1. Uniform means, constant scaling in X,Yand Z direction.

 

if 'Uniform' option is unchecked, the dialog shows its X, Y and Z factors as below.

here scaling will vary in each direction.

In this case, deformation is normalized in each direction (X, Y and Z Max normalization) and mapped with x,y and z length of bounding box size respectively .

Note: If the model is planar or linear, check 'Uniform' option for better visualization of deformation.

How to scale the model uniformly?

  • Click CAE | Scale Factor which pops up Deformation Scale Factor dialog.

 

 

 

 

  • Click Uniform check box which provides modified dialog as below.

 

 

 

 

  • Provide  a different scale value, say 2 in the edit box.

  • Click apply and observe the scaled deformation in the viewer as below.

 

How to scale the model in each axis?

  • Click CAE | Scale Factor which pops up Deformation Scale Factor dialog.

  • Provide different scale values for each axis in the corresponding edit boxes.

  • Click apply and observe the scaled deformation in the viewer as below.

How to scale deformation for Mode case animation data?

  • Load a mode case CAX file.

  • Select CAE | Animate.

  • Select CAE | Scale Factor

  • 'Normalize' option is visible and checked by default for mode case data.

  • The default value for mode case data is 10 % and for complex eigen data is 1 %,

  • Change the value to 20 % and click apply.

  • Notice the change.

  • Uncheck 'Normalize' option.

  • Usual scale factor option will be enabled. Enter 1 and click apply for true scale.
