Quick Explainer
What should a proper V&V report contain?
A complete V&V report documents: (1) Model description — geometry simplifications, material models, boundary conditions, and justifications. (2) Verification results — mesh convergence, iterative convergence, analytical comparisons. (3) Validation results — comparison with experimental data, uncertainty bounds, agreement metrics. (4) UQ — sensitivity to key assumptions. (5) Applicability statement — what the validated model supports and what it does not. Traceability is key: results must be reproducible from the documented setup.
What is model pedigree and why does it matter?
Model pedigree describes the history and validation basis of a simulation model: what it was originally validated against, how it was modified for the current application, and whether modifications take it outside the validated range. Critical for regulatory submissions — a model validated for subsonic aluminum structures has excellent pedigree for a new aluminum substructure but poor pedigree if now applied to supersonic composite structures.
