2491. Multibody Dynamics Simulation - Modelling the Imperfect Perfectly

      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

2492. FEM Mesh Generation Using CAD Surface Shape Recognition Technique

      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

2493. Future - Not Fantasy

      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

2495. Lee Margetts discusses the impact of affordable HPC

      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

2498. Effectively Communicating Innovative Ideas: Why Perspective Is Important

      If you look at the back of the quarter from New Hampshire, you will see a picture of the Old Man of the Mountain. Prior to its collapse in 1997, this naturally occurring rock formation had once depicted the profile of a man’s face when viewed from a certain perspective on the ground. Signs directing you to a specific viewing area were placed along the local highways. While standing at one of the designated viewing areas you could see the profile (pictured on the right). If you were standing anywhere other than one of the designated viewing areas, the profile was lost to you and looked like any other mountain; The proper meaning requires the right perspective....more

2499. FAQs

      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
