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
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
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

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
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

NAFEMS Americas and Digital Engineering (DE) teamed up (once again) to present CAASE, the (now Virtual) Conference on Advancing Analysis & Simulation in Engineering, on June 16-18, 2020! CAASE20 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, to share experiences, discuss relevant trends, discover common themes, and explore 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, and human enablers that will take past successful developments...more
This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada Resource Abstract This paper uses the results of a publicly available paper which validates mesh based computational fluid dynamics (CFD) methods for predicting oil flow in a closed gearbox to compare the same results for a particle based numerical method. In the original paper a standard FZG no-load power loss test rig containing a wheel and pinion partially submerged in oil was used. Multiple types of oil were each tested at several rotational rates to gather qualitative images of oil distribution and churning power losses. These results were then compared to numerical simulations performed in Ansys Fluent 18.0....more
The webinar recording can be viewed by clicking this link. The password can be obtained via the member download button. Engineering organizations must increasingly rely on computational simulation for design and predicted performance, reliability, and safety of systems. Computational analysts, designers, decision makers, and project managers who rely on simulation should have practical techniques and methods for assessing simulation credibility. This webinar presents an introduction to the topics of verification, validation, and predictive capability. These topics are applicable to essentially all engineering and science applications, including fluid dynamics, heat transfer, solid mechanics,...more
