The IoT movement is driving an increasing amount of electronics and electrical systems into today's products. That trend presents new challenges when it comes to predicting and validating performance. Has signal integrity been checked? What about the thermal loads? Simulation stands as a solution to these issues, but does it really pay off? This webinar will answer that question. Information presented in this webinar will be based on the results of the survey developed by Chad Jackson of Lifecycle Insights....more
Simulation, in ten years, won’t be recognizable to today’s practitioners. Vendors are consolidating, leading to technical and business changes. Hardware choices increasingly include local, CPU/GPU, HPC and cloud (or not), affecting where and how simulations are run. And the way enterprises use simulation is changing, too. In this webinar we explore these topics and ask 5 important questions to help you navigate these changes. About the Presenter Monica Schnitger, President and Principal Analyst, Schnitger Corporation. Monica is an industry analyst focusing on the software tools to create the objects that surround us. She has developed industry forecasts, market models and market statistics...more
Ms. Ioana Tircomnicu-Unga: NAFEMS Eastern Europe Steering Committee Member Judit Oldal, NAFEMS - July 27th 2021 We are pleased to bring you a series of posts about the NAFEMS Eastern Europe Steering Committee members so you can learn more about them. First up is Ms. Ioana Tircomnicu-Unga. Tell us briefly about yourself Passionate about how digital technologies can help companies in almost every industry improve products and efficiency, I work closely with national and international companies to support them implement the right technologies, while, from an internal point of view, I assemble the sales and technical support teams. It is an amazing job and an amazing time to do it! When...more
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
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
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

Since June 2022, ASSESS as been part of NAFEMS....more
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
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
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
