Ensuring Quality: Verification, Validation & Sanity Checks

For any engineering analysis, especially those involving complex simulations, ensuring the quality and reliability of results is paramount. Consultants prioritize rigorous verification and validation (V&V) protocols.

Model Verification: Are We Solving the Equations Correctly?

Verification focuses on ensuring that the numerical model accurately solves the underlying mathematical equations. Key checks include:

Mesh Independence Studies: Performing the analysis with progressively finer meshes to ensure that the results (e.g., peak stress, maximum deflection) converge to a consistent value, indicating that the mesh is sufficiently refined. This is critical for tools like Abaqus, ANSYS, and OpenFOAM.
Boundary Condition & Load Checks: Verifying that all applied boundary conditions and loads are correctly defined and applied. This often involves checking reaction forces, total applied load, and initial deformation patterns.
Convergence Criteria: For iterative solvers (common in non-linear FEA or CFD), ensuring that the solution has converged within acceptable tolerance levels for residuals (e.g., flow velocities, energy conservation).
Element Distortion & Quality Checks: Examining mesh quality metrics (aspect ratio, skewness, Jacobian) to ensure elements are not excessively distorted, which can lead to inaccurate results.

Model Validation: Are We Solving the Right Equations?

Validation addresses whether the numerical model accurately represents the real-world physical phenomenon. This often involves comparing simulation results against known benchmarks:

Comparison with Analytical Solutions: For simplified cases or sub-models, comparing simulation results against closed-form analytical solutions (e.g., beam deflection formulas, simple heat conduction).
Comparison with Experimental Data: The most robust form of validation involves comparing simulation predictions with physical test data from prototypes or existing systems.
Comparison with Hand Calculations: Performing basic hand calculations for critical parameters (e.g., overall force balance, approximate stress levels) to check the order of magnitude of simulation results.
Peer Review & Independent Checks: Having another experienced engineer or consultant review the model setup, assumptions, and results.

Sanity Checks & Common Pitfalls

Beyond formal V&V, constant sanity checks are essential:

Expected vs. Actual Results: Always question if the results make physical sense. Are deformation patterns logical? Are stress concentrations where you’d expect them? Are magnitudes reasonable?
Material Properties Sensitivity: Understanding how sensitive your results are to variations in material properties.
Units Consistency: A fundamental yet often overlooked check – ensure all input parameters and software settings use a consistent system of units.
Common Mistakes: Beware of over-constraining or under-constraining models, applying incorrect load directions, or misinterpreting software outputs.
