2721. An Introduction to Dynamic FEA

      An Introduction to Dynamic Finite Element Analysis View webinar slides (PDF) (NAFEMS Members) Many problems facing designers and engineers are dynamic in nature. The response of a structure cannot be simply assessed using static assumptions. The nature of the problem may be to understand the resonant frequencies of your design, so that key driving frequencies such as equipment rotational speed, acoustic or external pressure frequencies, ground motion frequency content or vehicle passing frequency. Your design may face external driving forces from adjacent components; cams, push rods, pistons or from vehicle input sources such as a bumpy road, wave loading, air pressure or inertial forces....more

2722. Particle Methods

      Particle Methods Technical Group Particle methods are a class of numerical techniques that can be used to simulate engineering systems and components by representing the domain as a collection or particles. The particle method approach differs from conventional mesh-based methods (such as the FE method) as the connectivity of particles is not fixed and is dependent on the location of the other particles at any given point in time. Particle methods have a wide range of applications both in the fluid and structural domain. They offer unique advantages for modeling phenomena that are challenging to address with traditional grid-based methods. They are well suited to simulate systems that undergo...more

2723. The Awakened Enterprise – A Vision for Machine-augmented Mindfulness

      Translating the massive amounts of analysis data generated daily by simulation engineers into smart business decisions is a challenge. Time pressures, resource constraints, and knowledge gaps often force teams to make critical decisions without making full use of this vital resource. In this webinar, GE Aerospace's Rick Arthur will show you a better way forward. You'll discover how leading organizations are combining human expertise with AI-powered systems to: Make faster, more confident decisions even when dealing with uncertain or incomplete data Reduce costly design iterations by better understanding system sensitivities upfront Bridge organizational silos that often derail complex engineering...more

2725. 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

2726. 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

2727. 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

2728. 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
