A Hands-On Introduction to ADAMS
Verification and Validation in Computational Mechanics
Pre-Congress Short Course
Tuesday, July 31, 2001
2 - 6 PM
Hyatt Regency, Dearborn
Course Description
This short course will summarize the terminology, methodology, and procedures for verification and validation in computational mechanics. The subject material will be generally applicable to all areas of continuum mechanics, but the emphasis will be on fluid dynamics and solid dynamics. Terminology to be discussed includes: definitions of verification and validation accepted in engineering, definitions of verification and validation used in other fields, certification, accreditation, prediction, calibration, software quality assurance, and uncertainty and error in computations and experiments. General verification assessment procedures for finite element, finite difference, and finite volume methods will be summarized, such as, grid and time-step convergence, iterative convergence, consistency tests, and the use of analytical and benchmark numerical solutions. Validation assessment procedures will be summarized, specifically the use of hierarchical experiments in validation (unit problems, benchmark cases, subsystem cases, and the complete system). An example will be given showing how a complex engineering system with coupled physics is separated into each of the hierarchical levels for validation. Six key characteristics will be discussed for the design and execution of high quality validation experiments. Quantification of comparisons of computation and experiment is introduced through the use of validation metrics. The tutorial will close with a discussion of how a code validation database is related to uncertainty estimation in code predictions.
The tutorial is appropriate for both computationalists and experimentalists working in confidence assessment in computational mechanics. Managers who are responsible for the reliability and accuracy of analyses in computational mechanics should also attend. Most topics are discussed at the conceptual level so that detailed knowledge of numerical methods or experimental techniques are not required.

Instructor
Dr. William Oberkampf has 30 years of research, development, and applications experience in both computational and experimental fluid dynamics. He has worked in the field of verification and validation for the last 12 years and recently co-authored the first engineering standards document on the subject: "Guide for the Verification and Validation of Computational Fluid Dynamics Simulations" published by the American Institute of Aeronautics and Astronautics. He is one of the founding members of the new ASME Codes and Standards Committee for Verification and Validation in Computational Solid Mechanics. He is presently a Distinguished Member of the Technical Staff at Sandia National Laboratories.
