In mid-May 2023, ESRD’s Co-Founder and Chairman Dr. Barna Szabó will deliver a keynote presentation at the ASME VVUQ 2023 Symposium in Baltimore, Maryland, USA. Dr. Szabó’s presentation, entitled “Simulation Governance: An Idea Whose Time Has Come”, will focus on the goals and means of Simulation Governance with reference to mechanical/aerospace engineering practice.
The abstract of the keynote presentation is as follows:
Mathematical models have become indispensable sources of information on which technical and business decisions are based. It is therefore vitally important for decision-makers to know whether or not they should rely on the predictions of a particular mathematical model.
The presentation will focus on the reliability of information generated by mathematical models. Reliability is ensured through proper application of the procedures of verification, validation and uncertainty quantification. Examples will be presented.
It will be shown that mathematical models are products of open-ended evolutionary processes. One of the key objectives of simulation governance is to establish and maintain a hospitable environment for the evolutionary development of mathematical models. A very substantial unrealized potential exists in numerical simulation technology. It is the responsibility of management to establish conditions that will make realization of that potential possible.

“The p-type element has been used to great advantage in the finite element system ESRD StressCheck, [26]. 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”, [27]. 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.”
