What Our Members are Saying Discover how being part of the NAFEMS Community empowers professionals accross a wide array of industries. Find out from our members how the different resources such as training courses, webinars, Technical Working Groups, the PSE certification help them in advancing their skillset and drive innovation. Our graduate training program in FEA modeling and simulation fundamentals has received strong demand from working professionals seeking to strengthen skills for career advancement or a pivot to a new industry. I’ve talked with many program participants and their employers and have consistently heard that they value our NAFEMS membership and the credibility conferred...more
You may be wondering, ‘Why should I be bothered about a Modelling and Simulation Strategy? I’m too busy actually doing the job! Our organisation just wants the results!’ The answer is that simulation is highly likely to be critical to your organisation’s success. It’s also highly complex and impacts the whole organisation. It consumes significant budget, resources and time throughout your product creation and delivery processes. Most importantly it impacts the performance of the products you deliver to your customers....more
2. Hardware Requirements General Considerations In this chapter, we’ll discuss what hardware will provide you with the best finite element software performance. We will start off by providing you with an overview of the components and systems that we will be covering in more depth throughout the chapter. We will also start off with some basic guidelines to help you optimize your workstation configurations. (Please consider that this course has been created in 2020, some hardware specific considerations may not be relevant anymore.) Processing This section will provide some guidance as to which CPUs are most ideal for FEA as well as what options to consider. We will also go into some...more
Lee Margetts discusses the impact of affordable HPC with Desktop Engineering Lee Margetts, chairman of the NAFEMS HPC Working Group, along with Alan Chalker from the Ohio Supercomputer Center discussed the impact of affordable HPC (High Performance Computing) with Desktop Engineering Contributor, Kenneth Wong. Alan Chalker and Lee Margetts, Image: Desktop Engineering The democratization of HPC is expected to change the way engineers work. You can tap into HPC resources available on-demand without owning or buying HPC hardware. You will hear about Alan Chalker's experience, which is one you might have to face yourself when running a simulation. Lee Margetts will tell us what the roadblocks...more
This Presentation, ASSESS Congress 2016 - Align Theme, is from 2016. NAFEMS & ASSESS members can view / download when logged in. The ASSESS Initiative is a broad reaching multi-industry initiative with a primary goal to facilitate a revolution of enablement that will vastly increase the availability and utility of Engineering Simulation, leading to significantly increased business benefits across the full spectrum of industries, applications and users. Since June 2022, ASSESS as been part of NAFEMS....more
Multibody Dynamics Simulation - Modelling the Imperfect Perfectly 5-minute read Patrick Morelle - September 14th 2023 Modeling a pair of gears does not seem too complicated a task. Coupling two angles of rotations, describing the geometry of the gears, really, nothing too complicated. It could all be described as a routine job for any and every MBD software in the world. Now, let us ask ourselves: What could be the role of a “simple” MBD model of a gearbox? Clearly, the first purpose of such a model is to reproduce the kinematics of such an assembly of gears, making sure the speed of rotation of the shafts is what it is supposed to be, which involves the size and geometry of all the...more
This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada Resource Abstract This paper describes how we generate FEM mesh from CAD models, either surface models or solid models, automatically. It is essential to use high-quality mesh for simulations since the result may vary depending on the input FEM mesh model. To assure the quality of simulation results, it is common to create FEM mesh models according to specific meshing rules. However, it usually takes enormous time and effort to modify FEM mesh model to maintain the quality of mesh following all of meshing rules if it is done manually. Generating mesh automatically using CAD surface shape recognition technique helps...more
Future - Not Fantasy Christoph Gümbel is widely regarded as one of the leading minds in digital prototyping and applied simulation methods for design and functional verification in the vehicle development process. He spent over 30 years with Porsche starting off as a software engineer, progressing to the role of head of CAE before becoming director of the virtual vehicle. He's now a consultant for the virtual development process and partner at Future Matters, one of Europe’s leading future research institutes. He spoke to NAFEMS’ David Quinn about why being a futurist is vital in today’s automotive industry....more
The ASSESS Initiative As of June 21st 2022, ASSESS is part of NAFEMS. ASSESS activities started in 2014, bringing together key players to guide and influence the software development and implementation strategies related to model-based analysis, simulation, and systems engineering, with the primary objective of expanding the use and business benefit of Engineering Simulation. Our new vision: “To lead every aspect of engineering simulation toward a more valuable and accessible future in the medium to long-term, leveraging the expertise and knowledge of top-level figures in industry, government, and academia.” FAQs What is ASSESS? Established in 2014, ASSESS is a broad reaching multi-industry...more
The "Usual Suspects" by Tony Abbey, FE Training I have been living in the US now for 13 years and occasionally I get a little nostalgic for the TV shows I grew up with in the UK. I found a DVD catalogue which included what in the US we call Cop Shows. The English vernacular I remember is Police Dramas. I ordered some old favourites such as “The Sweeney”, “The Professionals” and even an extraordinarily dated “Dixon of Dock Green”. As I sat through a few it struck me that there was often a common stage in the plot line. If a bank had been robbed, security van hijacked or similar knavery, the first thing our heroes did was to arrest the ‘usual suspects’. The thinking is pretty logical; if somebody’s...more
