3941. Where Do We Get the Courage to Sign the Blueprint?

      In this webinar the sources of error in numerical simulation and methods used for controlling them will be discussed. It is shown that when the size of the numerical errors in the quantities of interest (QoI) are not known then it is not possible to certify that a design is in compliance with the design rules. Therefore error estimation in terms of the QoI is an essential technical requirement. Error estimation is possible only when the mathematical model is properly formulated. This webinar will also highlight the differences between finite element modeling and numerical simulation. The creative aspects of formulating mathematical models and objective methods for ranking their performance are...more

      Digital Twin – An Engineers’ Perspective Abstract The term “Digital Twin” was defined by Dr. Michael Grieves at the University of Michigan around 2001. He defines “Digital Twin” as a digital replica of physical assets, processes and systems that have been manufactured. He promoted the idea of comparing a Digital Twin to its engineering design to better understand what was produced versus what was designed, tightening between design and execution. Digital Twin starts with the existence of a physical part –as early as a prototype exists, and they last until product end-of-life. We can put the digital twin life into three major phases: twins for designs, twins for manufacturing and twins for...more

3943. Blog: How Do I Switch It On?

      Blog: How Do I Switch It On? Excuse me, how do I switch it on? 19 March 2013 by Tony Abbey, NAFEMS Training Manager One of the most enjoyable aspects of the training that I carry out is the travelling involved. I have been very fortunate to teach in many countries around the world and to visit many interesting places. Often this involves flying into an airport, picking up a rental car and then heading off to my hotel on the first night. One of the great blessings has been the introduction of SatNav or GPS navigation aids. I always carry my own with me and like to have a backup iPhone or similar just in case. Finding a city centre, or very rural, hotel on a dark rainy night is now a lot...more

3944. An Al Co-Pilot for Structural and Thermal Modeling in Aerospace

      These slides were presented at the " Digital Tools for Transforming the Aerospace Industry " Seminar, held in Middleburg Heights, USA on 3-4 September, 2025....more

3945. Leveraging Scientific Machine Learning to Augment Engineering Modelling and Simulation

      What, exactly, is Scientific Machine Learning, and how can it enhance traditional simulation? What role does it play in building surrogate models like Neural Operators or Physics-Informed Neural Networks? This webinar explores the transformative potential of Scientific Machine Learning, a powerful approach that fuses the rigour of physics-based modelling with the adaptive power of data-driven algorithms. Discover how this synergy is bridging the gap between complex simulations and real-time decision-making, unlocking new potential in product development. The webinar will focus on enabling you to augment , not replace, your established simulation workflows. create highly accurate surrogate...more

3946. ASSESS Congress 2019 - Opening Remarks

      This Presentation, ASSESS Congress 2019 - Opening Remarks, is from 2019. NAFEMS & ASSESS members can view / download when logged in. The ASSESS Initiative is a broad reaching multi-industry initiative with a primary goal to facilitate a revolution of enablement that will vastly increase the availability and utility of Engineering Simulation, leading to significantly increased business benefits across the full spectrum of industries, applications and users. Since June 2022, ASSESS as been part of NAFEMS....more

3947. Simulating Metal Forming Processes – Material Characterisation

      Metal forming simulations are increasingly adopted by manufacturers to improve the quality and performance of products and processes while shortening development cycles so that these products can be brought to market earlier. Successful simulation of metal forming processes requires a range of input data about the geometry of the workpiece and tooling, the process forces and tooling motion and, above all, the characteristics of the workpiece material. The accuracy of the results depend on having a good understanding of this input data. In this webinar we introduce manufacturing process simulation methods for a range of metal forming operations and then review the material characterisation requirements...more

3948. Exploding Dough And Fun With Carrots

      Exploding Dough And Fun With Carrots by Tony Abbey, FE Training Welcome to my first blog for NAFEMS and an unusual title. It has been a very busy two weeks travelling and teaching the NAFEMS “Introduction to FEA” class in the UK and Holland. As usual each class was very different - depending on the background of the client company and the individuals attending. Both classes were fun, I always enjoy meeting fellow engineers and talking about FEA and engineering. Two or three days working with a group gives a great opportunity to find out about everyone’s background, what aspects of analysis they are involved with and the engineering behind the products or process. It is a privilege to have...more

3949. What About Quality?

      Presentation made by O. Widlund, M. Stallgard, J. Ask at the NAFEMS Nordic Conference 'Engineering Simulation: Best Practices, New Developments, Future Trends' that was held in Gothenburg, Sweden on 10-11 May 2016....more

3950. The Role of Manufacturing Simulation in Automotive Product Development – Upfront Evaluation of Formability and Cost

      This presentation was made at NAFEMS UK Conference 2018, Taking Engineering Analysis and Simulation to the Next Level". The NAFEMS UK Conference 2018 brought together all those involved in analysis and simulation from every corner of industry and academia, giving them an opportunity to advance their knowledge, give their organisations a competitive advantage, and a chance to be part of improving the technology itself. Resource Abstract Computer aided engineering methods have been applied to the simulation of manufacturing processes for many years. Techniques such as finite element analysis (FEA) and computational fluid dynamics (CFD) were applied to trouble shoot problems arising in production....more
