The credibility of a finite element model can be assessed by examining whether the model was built, solved, and checked appropriately for its intended use. Relevant checks may include hand calculations or benchmark solutions, mesh-convergence studies, sensitivity analyses, and comparisons with physical tests or measured behavior where appropriate. Verification addresses whether the mathematical model and numerical solution were implemented and solved correctly, while validation evaluates how well the model represents the real system for the intended application. The reliability of the conclusions also depends on the assumptions, input data, boundary conditions, material properties, and uncertainties in the analysis.
Mesh convergence is the process of determining whether a result approaches a stable value as the finite element mesh is refined. Different outputs, such as displacement, force, strain, or stress, may converge at different rates, so the study should focus on the quantities that support the engineering conclusion. Local stresses near sharp corners, point loads, idealized constraints, or other singular features may remain highly mesh-dependent and should be interpreted carefully rather than relying solely on the maximum plotted stress.
Verification evaluates whether the mathematical model and numerical solution have been implemented and solved correctly, including checks for numerical error, discretization effects, and convergence. Validation evaluates whether the model represents the relevant physical system accurately enough for its intended use, often by comparing predictions with experimental data, measurements, or other real-world evidence. A model can therefore be numerically well verified while still being an inadequate representation of the physical problem under investigation.
