The VVUQ 10.2 standard describes the role of uncertainty quantification (UQ) in modeling/simulation and experimentation. UQ in modeling and simulation includes consideration of model-form uncertainties, numerical solution uncertainties, model input uncertainties, and uncertainties in model-basis data. In addition, propagation of uncertainties is an integral part of UQ in modeling and simulation. UQ plays an important role in experimentation, therefore key considerations in planning validation experiments are discussed, since these experiments are specifically planned and performed to assess the predictive capability of a computational model. A brief discussion of UQ in hierarchical computational solid mechanics (CSM) models is provided, as well as an overview of the role of UQ in revisions to either the computational model or the validation experiment.
This Standard also addresses the role of UQ in model validation assessment, illustrated by several examples considering different validation metrics that include uncertainties. Because validation metrics incorporate uncertainties in both experimental measurements and model simulations, some consideration of uncertainties is required in establishing the corresponding validation requirements.
