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

Overview Modeling and simulation (M&S) are a well-established part of the engineering design process. M&S are also gaining traction in other product life cycle processes through concepts like certification-by-analysis and digital twins. These advancements and the widespread influence of M&S continue to add relevance to the question of how much to trust computational model predictions. The answer to this question can be extremely challenging to determine and strongly depends on the application. Even if there is Verification, Validation, and Uncertainty Quantification (VVUQ) evidence to build credibility in the model predictions, this information is often difficult to convey to the model end-users...more
“Digital twin” is currently a term applied in a wide variety of ways. Some differences are variations from sector to sector, but definitions within a sector can also vary significantly. Within engineering, claims are made regarding the benefits of using digital twinning for design, optimisation, process control, virtual testing, and lifetime estimation. In many of its usages, the distinction between a model and a digital twin is not made clear. "When I use a word, it means whatever I want it to mean": Humpty Dumpty in Alice’s Adventures Through The Looking Glass, Lewis Carroll. The danger of this variety and vagueness is that a poor or inconsistent definition and explanation of a digital twin...more
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
Presentation made by J. L. D. L. Gandaraat the NAFEMS Spain Seminar "Verification & Validation - Building Confidence in Simulation for Engineering Design" that was held in Madrid, Spain on the 18th of February 2016. Seminar Description It is becoming increasingly important these days that engineering simulation used for design answers the question: how do we know that the results are reasonably correct? The important quality assurance tools used to answer this are the processes of verification and validation and these need to be applied to the conceptual, mathematical and computational models used in engineering simulation. In simple terms verification is the demonstration that the mathematics...more

How To Use STEP Geometry for Engineering Analysis Due to the evolving nature of the engineering analysis and simulation market this publication no longer represents current best practice and has been archived. The document may be of historical interest and is therefore still available for purchase This guide is aimed at system managers who are implementing and supporting data exchange by purchasing STEP interfaces and users who want to communicate with customers and/or suppliers about using STEP for data exchange. The guide covers: What STEP interfaces are available What the parts and conformance classes cover How to choose which part and conformance class...more
