ADS-79D-HDBK Downloaded from https://www.everyspec.com K.4.3 General Considerations for Verification and Validation. The terms ―verification‖ and ―validation‖ have been used interchangeably in casual conversation as synonyms for the collection of corroborating evidence. In the context of modeling and simulation, per ASME V&V 10, ―verification‖ is the process of gathering evidence to establish that the computational implementation of the mathematical model and its associated solution are correct.
―Validation,‖ on the other hand, is the process of compiling evidence to establish that the appropriate mathematical models were chosen to answer the questions of interest by comparing simulation results with experimental data. Therefore, a complete and comprehensive V&V process should address both verification and validation of the model. A notional hierarchy of the V&V process for modeling and simulation, as recommended by ASME V&V 10, is shown in Figure K-3. The process consists of mathematical modeling and physical modeling branches. Design engineers follow the left branch to develop, exercise, and evaluate the model.
Testing engineers follow the right branch to obtain the relevant experimental data via physical testing. Modelers and experimenters collaborate in developing the conceptual model, conducting preliminary calculations for the design of experiments, and specifying initial and boundary conditions for calculations for validation. 193 TABLE K-I.
