This
task will show you how to create a white noise modulation.
A White Noise Modulation is a constant modulation (equal to one). |
 |
- Only available with the Generative Dynamic Response Analysis (GDY)
product.
- A Dynamic Response Case must have been previously inserted.
|
 |
Open the
sample56_1.CATAnalysis document from the samples directory. |
 |
-
Click White Noise
in the Modulation toolbar.
The White Noise Modulation dialog box appears.

A Modulations.1 set has been created in
the specification tree under the Finite Element Model.1
set.
 |
-
Modify the name of modulation you just have created, if
needed.
-
Click OK in the White Noise Modulation dialog
box.
|
 |
-
You can now define the load excitation set or the
restraint excitation set.
To do this, refer to the Dynamic Response Sets
chapter in this guide.
-
You can have several modulation objects (white noise
modulation or imported modulation) in the modulation set.
To know how to import a modulation from an existing file, refer to
Importing Frequency Modulation or
Import Time Modulation in this guide.
