Presentation made by I. Symington at the NAFEMS UK Seminar "Improving High Performance Computing (HPC) Adoption in Engineering Simulation" that was held in Manchester, UK on the 10th of February 2016. Seminar Description In recent years, a new business cliche has emerged: "To out compute is to out compete". In essence, the use of high performance computers for engineering simulation can help speed up design turnaround times, reduce time to market and increase competitiveness. The purpose of this seminar was to help promote the adoption of high performance computing throughout the engineering supply chain, from independent consultants to SMEs and large firms....more
Why Do Design Optimisation? ‘Optimisation’ is about selecting the best option from a range of possible choices. It is natural to consider this when designing a new product. As the old saying goes, ‘A job worth doing is worth doing well’. Why not produce a design that is the best in its class, if you have the means to do so? It may not cost any more in time and money to design and produce; and it may cost less. The customers for your product will be more please with it. Everyone will be happier, except your competitors. But how to make the selection, that is the question. Maybe in practise, you would settle for something that is some way short...more
This presentation was made at the NAFEMS Eastern European Seminar held in Budapest Hundary on November the 27th 2017. This seminar focused on the trends and the new methodologies of numerical simulation and answered the new objectives of the automotive industry.What are the new needs of the automotive industry and by what methods of numerical simulation will engineers be able to face these new elements?...more
This isn’t what I was going to write for this issue. In fact, I completed something else; it was about design decisions and how their results appear as if by magic in CAE feature trees. But it seemed to me that I was getting too negative in these pieces. You’ll hardly be surprised to hear that I think we have a few things to be negative about where we’ve got to as an industry. But we’ve also got a whole lot more to be pleased about, and maybe it’s better to look at that stuff more than occasionally. So, let’s look back at a reason we’ve got to be pleased with ourselves as an industry, and what our long dark nights of the soul have actually achieved. This article appeared in the January 2026...more
Verification & Validation – An Introduction 7-minute read NAFEMS SGMWG - August 26th 2021 In the first of a series, the NAFEMS Simulation Governance & Management Working Group hosted a discussion introducing the concept of Verification and Validation. As well as reading the conversation here, you can watch the video on YouTube, as well as listen to the audio on the NAFEMS Podcast. The discussion was hosted by Chris Rogers, Chair of the NAFEMS Simulation Governance & Management Working Group, alongside members of the group, William Oberkampf (WO), Gregory Westwater (GW), Keith Meintjes (KM), and Alexander Karl (AK). How would you define the terms ’Verification’ and Validation’? Q (GW)...more
Model Calibration and Model Validation - What's the Difference? A Discussion with the NAFEMS SGMWG 12-minute read NAFEMS SGMWG - March 22nd 2023 As part of an ongoing series, the NAFEMS Simulation Governance & Management Working Group present a discussion about the difference between model calibration and model validation. As well as reading the conversation here, you can watch the video on YouTube. The discussion was hosted by Gregory Westwater (GW, Emerson Automation Solutions) and William Oberkampf (WO, consultant), both members of the NAFEMS S imulation Governance & Management Working Group GW: Model calibration and model validation, how do you define each? And what's the distinction...more
Greenwashing Let's talk about sustainability. At its core, it is about doing what we can to slow the depletion of natural resources. How we do this varies by use case. We could redesign a product to use less steel or switch to renewable resources like wood. We can work on the problem via the supply chain, sourcing material closer to home so it requires less fuel to reach us. We could embrace circularity, designing a product that is intended to be recycled so its components can be reused. Beyond product design, we might redefine the production process to use less electricity or water. There are many possible actions, each doing its part to address what can sometimes seem like an overwhelming...more
The Evolving World of Simulation- When, How, How Much, and If 4-minute read Sinothile Baloyi - July 31st 2024 Many great innovations emerge from wars and other existential threats, why exactly that is is complicated, but perhaps at a simplified level, it’s something to do with the fact that when it comes to eliminating real threat to life, there is no cost too great. Computer simulation is one such innovation that found in war an accelerant. During the Second World War and following a course in wartime electronics, physicist John Mauchly wrote a memo proposing an all-electronic calculating machine, and that’s how ENIAC (Electronic Numerical Integrator And Computer), the first general-purpose...more
