ASC Program Elements

Based on the functional and operational requirements established by designers, analysts and code developers for greater fidelity of codes and models, this subprogram establishes a technically rigorous foundation for the credibility of code results. This sub-program interfaces with the Integrated Codes Sub-program to obtain regular, official code releases from the code projects. Verification activities assess code precision in implementing numerical approximations and assess the accuracy of these numerical approximations. Validation activities aid in the understanding and assessment of a model’s accuracy by comparing model predictions with experimental data. Quantification methodologies provide measures of the uncertainties associated with the simulations. Sound software quality engineering practices are used to ensure robust, efficient, and well documented software releases of the ASC codes. This sub-program collaborates with the Science and Engineering Campaigns and DSW to obtain experimental data for validation purposes. Final V&V assessment reports contain the standard deliverables of this subprogram.
