2771. What are Particle and Meshless Methods?

      There are still some problems that FE methods do not solve efficiently or accurately. In particular, FE methods are not ideally suited for solution of dynamic problems involving a large amount of deformation because an accurate solution requires regularly-shaped elements and the movement of the nodes can lead to mesh distortion and badly-shaped elements. One approach to avoiding the problems associated with mesh deformation is remeshing, where anew mesh of regularly shaped elements is created during the solution process. This approach is computationally expensive and has potential loss of accuracy as it requires the mapping of the solution from one mesh to the next which is why meshless or particle...more

2772. Multi-Physics Dynamic Modelling of an Electric Vehicle from Road to Battery

      Abstract The need to engineer robust electric powertrains for passenger cars and other land vehicles is clear. The design rules that were developed for ICE-driven vehicles no longer apply, yet the market is moving too quickly for similar design rules to be developed through iterative development of electric powertrains. Simulation is the only plausible route forward. ePowertrains are highly integrated, yet the effect of this integration is hard to simulate. At the concept stage the boundary conditions for the design of each sub-system is often poorly defined or over-simplified, and even at the full-system validation/sign-off stage the interaction between the different parts of the system is...more

2773. 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

2776. Considerations for New System Design using Additive Manufacturing as a Technology Enabler

      This presenatation was delivered at the NAFEMS UK Seminar "Design and Manufacturing of Additvely Manufactured Components" held on the 28th of September 2017. Additive Manufacturing (AM) offers many potential benefits over traditional manufacturing techniques. It enables the generation of complex geometries and lattice structures to make lighter components, can improve thermal performance through more flexible cooling design, avoids the need for expensive tooling for short production runs and may make mass customisation a reality as customers seek more personalised products. AM applications can been found in a wide range of industries, including Aerospace, Defence, Automotive, Sports and Medical....more

2777. How do we manage ES Digital Twins across a fleet of physical assets?

      This presentation has been held at the NAFEMS ASSESS Summit 2024 , on the 5th and 6th of March, 2024....more

2778. What the Codes Say

      What the Codes Say ... with respect to fatigue. The purpose of this section is not to try and conclude that any one code is better than another - rather, the goal is to provide diverse insight and understanding into DBA fatigue practice. This section discusses the following DBA standards and while the reader may decide to focus on a particular code of interest, it is recommended that the opportunity is taken to develop a breadth of understanding (to some extent) of all: PD5500 ASME VIII Div2 ASME III (brief mention) EN13445 Some other fatigue relevant standards and guidance, is also highlighted: BS 7608 BS 7910 In the Codes of Practice / DBA in Action section of the course, attention is...more

2779. The Evolving World of Simulation

      The Evolving World of Simulation Webinar Presentation (PDF) I Webinar Recording (WebEx) Note: The presentation and recording are only available to NAFEMS members. Overview Simulation is changing how we design and bring products to market, creating competitive advantages for companies that take advantage of these advances. We’ll talk about what happened in 2022 and what we can expect for 2023 — and ask essential questions to help you navigate these changes. This webinar was available for free to the engineering analysis community, as part of NAFEMS' efforts to bring the community together online. About our speaker Monica Schnitger - President and Principal Analyst, Schnitger Corporation...more

2780. Simulation Data Management

      Simulation Data Management Making the Data Work A hard-drive full of spreadsheets is the new paperwork filled filing-cabinet. Collating, managing, storing and reusing simulation data is key to successfully seeing the benefits of analysis and simulation throughout your organization. Knowing what you need, how to implement it, and how to get users to engage with it is vital for any system to succeed, and the benefits are substantial. NAFEMS is leading the way in examining best practice in simulation data management, and in providing users with the knowledge to choose, implement and review their tools and processes. Remember back in the day when a few gigs of disk space was a serious cost that...more
