4171. 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

4172. The Role of Manufacturing Simulation in Automotive Product Development - Upfront Evaluation of Formability and Cost

      Virtual Engineering is routinely used as a key tool in the development, optimisation, and verification of products alongside design guidelines and prototypes testing. For a considerable part of the process the only available assessments originate from simulations, engineers must therefore ensure the virtual results are not only delivered but also effectively used. This includes meeting several criteria such as timing, accuracy, robustness, limitations and suggestions appropriate to the project stage. Setting the quality requirements in this loop has been a common responsibility for the simulation specialists and the consumers of simulation results.Now virtual engineering is becoming more accessible...more

4174. 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

4175. How to – Model the Additive Manufacturing Process

      Over the last decade the Additive Manufacturing process has attracted a high level of interest due to the potential that the process has to revolutionise the way engineering companies design products. As well as offering rapid cycle times from initial concept to finished product it also allows previously unmanufacturable designs to be produced. However, even with AM, it is not possible to just “print” any shape out of metal. Distortion and cracking are recurring issues. Process simulation has a key role to play in resolving these issues and optimising the process parameters. This document provides guidance for people wanting to predict residual stress and distortion of metal additive manufactured...more

4176. 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

4178. Accurately Predicting Fiber Behavior through DEM and DEM-CFD Coupling Simulations

      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

4179. Evaluating Moving Particle Simulation Method Against Mesh Based Methods

      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

4180. Verification, Validation, and Predictive Capability: What's What?

      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
