Goal

• Explore CATIAs Generative Structural Analysis
  Workbench by performing a FEA on an assembled
  pressure vessel.

3
Step 1 Assembly Mesh

• Create Mesh
• For each part in assembly
• Small enough so that the tetrahedron mesh is
  uniform
• Large enough to minimize computation time

4
Step 2 Connections

• Create connections between the parts of the
  assembly
• Add analysis connections between parts
• Add connection properties for each of the
  analysis connections

5
Step 3 Loads and Restraints

• Create Loads
• Loads should accurately represent actual
  conditions.
• Create Restraints
• Lines or faces can be restrained from rotation or
  translation
• How an object is restrained will have a large
  effect on the results of an FEA
