AA&S 2019 Training – How Do You Verify the Accuracy of Engineering Simulations?
Abstract: This 2-hour training course will review strategies for verifying the accuracy of engineering simulation data, including best practices and common pitfalls engineers may encounter when assessing the quality of their engineering simulation results. The course will focus on the four key quality of solution checks that should be performed to confirm solution verification of detailed stress results. We will examine a variety of publicly-available and industry-applicable case studies, benchmarks and industry examples, to determine the most efficient and reliable methodologies to perform solution verification.
Originally presented as a training course at the 2019 AA&S/PS&S conference in Washington, D.C.

“The p-type element has been used to great advantage in the finite element system ESRD StressCheck®, . This software provides the engineer with the means to conduct solution verification in an extremely straightforward manner by simply increasing the degree of the element, monitoring convergence and using Richardson extrapolation reliably to estimate the error. This can be conducted automatically by the software thereby enabling the engineer to concentrate on the engineering rather than the simulation. StressCheck® has also been used to develop ESRD’s Handbook and Toolbox applications. The first of these provides engineers with a repository of parameterised standard problems of the type found in texts like Roark’s “Formulas for Stress and Strain”, . The second, Toolbox, is a tool that can be used to parameterise a company’s range of components for rapid and reliable analysis by non-expert analysis. Toolbox then is an exemplary of the way in which the democratisation of simulation can be applied.”
