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 global aviation, aerospace, and defense industries face unrelenting pressure for ever-increasing levels of operational performance, lifecycle reliability, and mission robustness in their products, platforms, and programs delivered to commercial and military customers. This is occurring concurrently with greater demand for overall system performance that is faster, lighter, quieter, smarter, greener, and more connected [...]
Compliance with ASME and NASA standards on verification, validation, and uncertainty quantification (VVUQ) is often taken as sufficient evidence that simulation results can be trusted. This is a mistake, however. Compliance alone does not answer the question that truly matters to decision-makers: Are the predictions reliable enough for the decision at hand?
Selecting the simplest model for an analysis is not always trivial for aerospace engineers. A Hierarchic Modeling framework eases this burden by providing support for virtual experimentation.
In this S.A.F.E.R. Simulation article, we explore the concept of Hierarchic Modeling, some practical applications of Hierarchic Modeling, and the importance of implementing a Hierarchic Modeling framework in CAE software tools to support the practice of Simulation Governance.
“At DST Group, we have effectively used StressCheck over the last 10 years to determine accurate stress intensity factors. The results have been used to improve our residual strength and structural life estimates for aircraft in service with the Royal Australian Airforce, including C-130, P-3C and F/A-18 A/B. We have found it to be extremely easy to use and a very versatile code with which to create parametric models.
