43. Frequently asked questions

    Frequently Asked Questions The answers to 50 frequently asked questions can be found in the pdf file available at the link below. Frequently Asked Questions Questions include: Q1. In the notes section which explains Gaussian quadrature (integration) it is stated that ‘With many elements the use of the low order integration rule reduces element stiffness’. Can you explain to me how this comes about? Q2. Why and when can symmetry be used when creating a finite element model? Q3. What boundary conditions should I apply to symmetric models? Q4. In the notes section it is stated that a type of element distortion that can lead to errors in the FE solution is due to mid side nodes not being positioned...more

44. Leveraging Systems Thinking, MBSE and Simulation in the Design and Analysis of Highly Distributed Autonomous Vehicle Systems

    This presentation was made at the NAFEMS Americas Seminar "Model-Based Engineering: What is it & How Will It Impact Engineering Simulation" held on the 1st of October 2019 in Columbus Ohio Resource Abstract The increase in global urbanization presents significant traffic congestion and emission challenges. Ford sees these challenges as an opportunity to design smart Autonomous Vehicle Solutions that can actually help city planners design transportation systems that improve the quality of life for everyone. To accomplish this goal we are leveraging Systems Thinking, Model Based Systems Engineering and Virtual Simulation Analysis & Design to define the next generation of mobility solutions. ...more

45. Automotive Panel Discussion 2

    This discussion session took place at the 2021 NAFEMS World Congress Discussion topics Battery Simulation: - What is the latest in battery technology development (w.r.t, range extension, fast charging, wireless charging)? Is numerical simulation helping? - One critical aspect of battery is Thermal Runaway. Today there have been several presentation on this! Are the current CAE methods adequate? Or are they still major gaps in simulation. - What about the simulation of battery aging effect on its efficiency? Autonomous Driving 1: With respect to ADAS and Autonomous development, is numerical simulation recognized by the industry as a critical path to delivering these technologies? Or is the industry...more

47. Modelling Structural Failure - What does it Mean to You?

    Modelling Structural Failure What does it mean to you? 1-minute read NAFEMS Computational Structural Mechanics Working Group - August 8th 2022 NAFEMS' Computational Structural Mechanics Working Group (CSMWG) are excited to see “Modelling Structural Failure” as one of the topics being covered at the NAFEMS World Congress 2023 , as it’s one of the main areas of interest for the group. But the more we thought about it, the more we realised that there was a lot of different ways of looking at the topic. We decided to poll our own members about what aspects of failure and modelling were of most interest, and came up with a list of questions to capture what we wanted to know. The answers...more

49. Nonlinear FEA the Smart Way: Designing Beyond the Obvious

    Nonlinear FEA the Smart Way: Designing Beyond the Obvious Dipl.-Ing. Dr.techn. Lukasz Skotny CEO / Lead Designer / FEA Course Creator at Enterfea Tutor biography Hey, my name is Łukasz Skotny. I studied civil engineering in the Wrocław University of Technology, where I’ve made a Ph.D. in the field of shell stability. I’ve been an academic teacher for a decade in the field of designing structural steel structures. Parallel to my Ph.D. I started my first design company (structural field). Right now, Enterfea is a leading company in the region providing high-end Nonlinear FEA designs to our Customers. At the same time, I’m running a blog, and I offer online and offline training in Finite...more

50. What Is Convergence?

    What Is Convergence? Convergence is a major issue with the use of CFD software. Fluid mechanics is involved with non-linear processes, dealing with inherently unstable phenomena such as turbulence. CFD software is intended to simulate these physical processes, and therefore is subject to the same issues as the processes it is trying to represent. As such it is not guaranteed that there will be a steady-state ‘converged’ solution to a problem. Computational Fluid Dynamics problems in general are non-linear, and the solution techniques use an iterative process to successively improve a solution, until ‘convergence’ is reached. Convergence can mean many things to many people. One definition [...more
