Recap Exercises
1. Pre-Processing Recap Exercise
Load CAT_GPF_pre-processing_recap_exercise.CATPart Under "Generative Shape Design" workbench:
• Click on the "Apply Material" icon • Apply "Aluminum"
Under the GPS workbench:
• Double-click
• Set a size of 10mm, a SAG of 1mm ans check Parabolic element types. Click on Ok
• Click on the clamp icon
• Select this surface:

• Apply –3000N on Z direction • Click on Ok
Below is what you should obtain:
In this exercise, you have seen how to apply two types of restraints and one load on a part. You should now be able to manage the other fundamental pre-processing tools
Load the previous CATIA Document or “catgps_Hanger_2.CATAnalysis” Before you trust in the results, it is important to evaluate their relevance. Consequently, the first thing to do is to check the estimated local error.
3.1 - You will create a Precision image
• Click on Precision icon in the Image toolbar
• A symbol is created in the specification tree:
3.2 - Now you will ask CATIA to localize the error extrema
• Click on the ‘Image Extrema’ icon in the Analysis Tools toolbar • Request maximum of 2 absolute values and click on OK
3.4 - You will try to determinate what is the Max. stress in your hanger
• Click on the Image Extrema icon
• Request a maximum of 2 global maximum values.
• Select the Von Mises Stress in the tree:
You obtain:
The extrema features appear in tree.
You can read that the max. Stress is about 6.2e7Pa. The aluminum yield strength is 9.5 .107 N/m2 (see Information box above) You could conclude that the hanger would not plastically deform under these conditions However, you need more accurate results to make sure.
