2541. 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

2543. 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

2544. 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

2546. The “Usual Suspects”

      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

2549. What Are the Chances of the Ship Snapping? Considerations When Using Probabilistic Analysis

      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

2550. 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
