Inserting a Frequency Analysis Case 

This task will show you how to insert a Frequency Analysis Case.
Creating a frequency analysis case means that you require a computation of eigen frequencies by referencing restraints and non-structural masses.

Remember that we use the Materials view mode.
If needed, select View > Render Style > Customize View and select the Materials option in the Custom View Modes dialog box.

1. Select Insert > Frequency Case.

   The Frequency Case dialog box appears with the possibility to either use the existing Analysis case as Reference or create a Frequency case with New feature.

2. Click OK.

   A new Analysis solution and the standard structure of Analysis specification tree is displayed. The Finite Element Model contains a Frequency Case, which contains empty Restraints and Masses object sets, along with an empty Frequency Case Solution.1 object set.

Remember that if you selected Start > Analysis & Simulation > New Generative Analysis from a CATPart document containing the part without any material, the material library will appear directly for an easy material selection.
