How do you validate part designs using CATIA?

Use the GSA (generative structural analysis) workbench to simulate and analyze the mechanical behavior of parts under various conditions. This process ensures that your design meets performance requirements before manufacturing. Here’s how you can perform part validation:

1. Access the generative structural analysis workbench
   • Navigate to start > analysis & simulation > generative structural analysis.
   • Ensure you have the required license:
     • For PLM Express configurations, you need the GAE or FAX add-ons, which include GPS (generative part structural analysis) for parts and GAS (generative assembly structural analysis) for assemblies.
     • For P2 platforms, licenses like SA2, GPS, or GAS are required.
2. Prepare your part for analysis
   • Open the part you want to validate in CATIA.
   • Apply material properties to the part:
     • Right-click on the part in the specification tree, select properties, and assign a material with defined density and mechanical properties.
3. Define the analysis setup
   • In the GSA workbench:
     • • Apply Restraints: Define fixed supports or other boundary conditions to constrain movement.
       • Apply Loads: Add forces, pressures, or moments acting on the part.
       • Mesh the Part: Generate a finite element mesh to discretize the geometry for analysis.
4. Run the simulation
   • Click on the compute button to start the simulation.
   • CATIA will calculate stress, strain, displacement, and other parameters based on your setup.
5. Interpret results
   • Use post-processing tools to visualize results:
   • View stress and displacement contours to identify critical areas.
   • Evaluate whether stresses exceed material limits or if deformations are within acceptable ranges.
6. Refine design if necessary
   • Based on the analysis results, modify your part design to address any weaknesses or inefficiencies.
   • Iterate through the analysis process until your design meets all performance criteria.
