Journal of Verification, Validation and Uncertainty Quantification
Purpose and Scope:
Papers submitted to the Journal must address one or more of the following areas:
Code Verification, Calculation Verification,
Validation, and Uncertainty Quantification
Code Verification: the assurance that code outputs converge to analytical solutions, particularly in terms of the rate of reduction of discretization errors (i.e., the order of accuracy). Examples of such verification often use the method of manufactured solutions as well as analytical solutions.
Calculation Verification: the estimation of numerical errors in simulation models due to discretization (typically time and/or space), incomplete iterative convergence, statistical convergence, and response surface approximations. Discretization errors are commonly estimated using Richardson extrapolation with systematic mesh refinement, residual-based methods (e.g., error transport equations, defect correction, adjoint methods), or by increasing the order of accuracy of the basis function representations.
Validation: the adequacy of a model to represent the reality of interest. Papers that focus on validation must involve assessment of models (e.g., by estimating model form uncertainty) through comparison to physical observations (i.e., experimentation). Acceptable comparisons require that both experimental and simulation results be accompanied by relevant measures of uncertainty from both sources.
Uncertainty Quantification (UQ): includes both the propagation of input/parametric uncertainty through models to the outputs of interest as well as methods for aggregating and conveying uncertainty from different sources (input/parametric uncertainty, numerical uncertainty, model form uncertainty). It is expected that papers that focus on uncertainty propagation will use modern and well defined statistical approaches to quantify this source of uncertainty. As UQ is a fundamental component of V&V, papers addressing this topic are a major aim of the journal.
