Workflows - FEA
How do we simulate our designs?
• 1) Physical Test -> Replicate
• 2) How it’s used in real life -> Replicate
• 3) MBD to Linear Static Analysis to Optimisation

Multi-Body Dynamics
9
• To understand part assembly mechanisms
• To comprehend motion characteristics
• To design for its intended use
• To find generated loads on each component
• To take it through for a structural analysis
