Outline
• Why validate • Validation – how it works • Using validation through the simulation cycle • Best practice

What is Verification?
• Simulations use mathematical models to replicate physical reality • Verification is confirmation of mathematical model • Unit element test checks that finite element behaves realistically

What is Validation?
• Confirmation of everything else • Choice of element type • Mesh size effect • Simulation settings • Material data & model • Material parameter conversion

Requirement for high-fidelity simulation
• Correctly represent the real-life scenario • Application of hi-fi simulation
• Late-stage prototyping • Additive manufacturing • Digital twinning

When to validate?
• Before starting work on real product • Whenever you change/modify a simulation parameter
• Finite element • Mesh size • Material model

Step 2 – Start making parts
• Take original design • Load case • Perform topology optimization • Print
Original parts
3D printed parts
Optimize

How it works
• Set up experiments and simulations in PICSCI • Perform test > drop data into PICSCI • Stage simulation
• Record simulation parameters and variables in PICSCI • Perform simulation > drop data into PICSCI
• Use Analyzer module to measure simulation accuracy • Iterate as needed to explore best material models and parameters • Deliver to client
• Validation Report • Simulation file • CAE Material file(s)

How to do it
• If you change your simulation parameters, element configuration, or material model, you can re-validate to assess the impact on your simulation
• Go to CAETestBench.PICSCI • Make a copy of the simulation • Download our simulation file and material card • Modify inputs as needed • Run simulation • Upload new simulation data, parameters and variables • Use Analyzer module to compare simulation to experiment • Iterate as needed to explore best material models and
parameters
