ASME (American Society of Mechanical Engineers) Verification, Validation and Uncertainty Quantification
Verification, Validation and Uncertainty Quantification (VVUQ) are the processes that determine if sound procedures were adhered to when forming a computational model and quantifying the parameters (physical and numerical) for analysis.[1]
Standards involving Verification, Validation and Uncertainty Quantification (VVUQ) are developed and maintained by the ASME V&V Standards Committee on Verification and Validation in Computational Modeling and Simulation. The V&V Standards Committee operates under the Board of Standardization and Testing. The V&V Standards Committee consists of members with balanced representation from a range of interest categories that include Designer, Laboratory, Producer/Manufacturer, Regulatory/Government, and Consultant.[2] The V&V Standards Committee and Subcommittees meet at a different times and locations during the year. All meetings are open to the public.
History[edit]
The credibility and correctness of computational results have become increasingly important as computational science has matured. In order to better assess the credibility of computational models, government agencies and professional societies have provided direction in the terminology and concepts of verification and validation.[3][4]
In 1999, a Verification & Validation specialty committee was created under the United States Association for Computational Mechanics (USACM). This led the way to forming a V&V standards committee under ASME, which operates under the guidelines of the American National Standards Institute (ANSI).[1]
In 2001, ASME’s Board of Performance Test Codes, which is now the PTC Standards Committee under the Board of Standardization and Testing, approved the committee’s charter. The designation and title assigned to the committee was PTC 60 (now V&V 10) Verification and Validation in Computational Solid Mechanics. PTC 60's foundational document, Guide for Verification and Validation in Computational Solid Mechanics, was ANSI approved in 2006.[1][3]
The V&V 20 (previously PTC 61) committee achieved ANSI approval of its standard regarding verification and validation in computational fluid dynamics and heat transfer in 2009. This standard specifies a verification and validation approach that applies concepts presented in the ISO Guide to the Expression of Uncertainty in Measurement.[5]
In 2018, the V&V 40 committee, which was formed in 2011, achieved ANSI approval of its standard that builds off of the V&V 10 and V&V 20 standards documents in order to provide guidance in evaluating the credibility of computational modeling for use throughout the life cycle of medical devices.[6]
ASME V&V Standards Committee Charter and Subcommittees[edit]
The Charter of the V&V Standards Committee is: Coordinate, promote, and foster the development of standards that provide procedures for assessing and quantifying the accuracy and credibility of computational models and simulations.
Underneath the V&V Standards Committee, each of the below V&V Subcommittees is involved in writing the proposals for standards development in Verification and Validation of Computational ...
Solid Mechanics (V&V 10)
Fluid Dynamics and Heat Transfer (V&V 20)
Simulation of Nuclear System Thermal Fluids Behavior (V&V 30)
Modeling of Medical Devices (V&V 40)
Modeling for Advanced Manufacturing (V&V 50)
Modeling in Energy Systems (V&V 60)
