3951. Managing Simulation Quality and Data at the UK Atomic Weapon Establishment

      This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada Resource Abstract In a Comprehensive Nuclear-Test-Ban Treaty (CTBT) era, simulation has widespread use across Physics, Material Science and Engineering at the UK Atomic Weapons Establishment (AWE). The engineering analysis team covers a wide scope of simulation topics including FEA/FVA of solid mechanics, structural dynamics, hypersonic CFD, thermal and blast effects. This in turn creates a broad range of data from a variety of engineering software tools. With increasing emphasis on coupled Multiphysics techniques and parameter sensitivity studies, an enormous amount of data is generated and is increasingly more difficult...more

3952. Techniques for modelling joints: A review of Static Design Approaches

      Structures are built-up from components connected by joints. For a structure with a vibration duty there are many uncertainties: - Can static joint design be used for dynamic design? - What is the dynamic stiffness of a joint? - How much damping is provided by a joint? - How do you model the dynamics of joints in simulation codes? - Can joints be designed to assist structural dynamic? - How repeatable and predictable is the behaviour of a joint? - Can joints be simplified to reduce weight and complexity? Research into these issues has received growing attention and some answers are now available. This workshop introduced the problems, the current knowledge, some approaches and some solutions....more

3953. AI in Engineering & impact on validation

      The presentation titled "AI in Engineering & Impact on Validation: Standards and Best Practices for Ensuring the Credibility of Numerical Simulations" was delivered by Vivien Clauzon and Raphaël Meunier. It focused on integrating Artificial Intelligence (AI) in engineering, particularly in high-performance computing and numerical engineering at Michelin. The presentation highlighted Michelin's three domains for sustainable growth: Tires, Around Tires, and Beyond Tires, focusing on a range of services from automobile to mobility intelligence. The speakers emphasized Michelin's approach to ensuring quality products, incorporating knowledge, product specifications, design, labs, and market considerations....more

3954. Uncertain Knowledge: A Challenge Problem

      Uncertain Knowledge: A Challenge Problem 7-minute read NAFEMS Stochastics Working Group - June 16th 2022 The NAFEMS Stochastics Working Group (SWG) has developed a guide entitled "What is Uncertainty Quantification (UQ)?" [1] describing the basic steps and definitions of Uncertainty Quantification, it has also hosted several discussions and webinars around the topic. Recently, the group updated the definitions of the Probabilistic Analysis [2] as part of the NAFEMS Professional Simulation Engineer (PSE) certification and is now working on developing related training and educational resources. In addition, the SWG has launched several challenge problems [3] in the area of probabilistic analysis...more

3955. Challenges of Simulation Technologies in a Fast-Changing Automotive World

      NAFEMS Americas hosted its biennial regional conference, formerly known as CAASE, on June 21-23, 2022, face-to-face, at the Indiana Convention Center in Indianapolis, Indiana! The NAFEMS Americas Regional Conference 2022 (NRC22 Americas) brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, sharing experiences, discussing relevant trends, discovering common themes, and exploring future issues, including: What is the future for engineering analysis and simulation? Where will it lead us in the next decade? How can designers and engineers realize its full potential? What are the business, technological,...more

3957. Using Digital Twins to Accelerate Product Development – A Beginners Guide

      Abstract Digital Twins have predominantly been applied to predictive maintenance of high value, low downtime assets. However, realising their full benefit as part of the product development process remains unclear. The main challenge for simulation teams is not creating good models, but the establishment of a new workflow that can make use of connected product data. Indeed, creating a compelling case for a product to be connected in the first place, and provide meaningful data, can be a major hurdle. To overcome these challenges, a proof of concept is initially required to clearly demonstrate benefit to the business, and ultimately the customer. Simulation and product development teams are well...more

3958. Systems Modeling & Simulation Standards in General, and SysML v2 in particular

      Systems Modeling & Simulation Community Meeting Systems Modeling & Simulation Standards in General, and SysML v2 in particular Tuesday 11 April 2023 | Online 08:00 PST (Los Angeles) | 11:00 EST (New York) 16:00 GMT (London) | 17:00 CET (Berlin) Join Here Since the Systems Modeling & Simulation Standards Focus Team has been dormant over the last couple of years, it's time to revive it and provide an overview of what the Systems Modeling & Simulation Working Group has available from the past, and what roadmap could be envisioned for the future, as standards remain an essential enabler of multidisciplinary systems modeling & simulation. In a second part of the presentation, an overview will...more
