This Presentation, ASSESS: Understanding a Generative Design Enabled Paradigm Shift, is from 2020. NAFEMS & ASSESS members can view / download when logged in. The ASSESS Initiative is a broad reaching multi-industry initiative with a primary goal to facilitate a revolution of enablement that will vastly increase the availability and utility of Engineering Simulation, leading to significantly increased business benefits across the full spectrum of industries, applications and users. 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
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

This presenatation was delivered at the NAFEMS UK Seminar "Design and Manufacturing of Additvely Manufactured Components" held on the 28th of September 2017. Additive Manufacturing (AM) offers many potential benefits over traditional manufacturing techniques. It enables the generation of complex geometries and lattice structures to make lighter components, can improve thermal performance through more flexible cooling design, avoids the need for expensive tooling for short production runs and may make mass customisation a reality as customers seek more personalised products. AM applications can been found in a wide range of industries, including Aerospace, Defence, Automotive, Sports and Medical....more

What the Codes Say ... with respect to fatigue. The purpose of this section is not to try and conclude that any one code is better than another - rather, the goal is to provide diverse insight and understanding into DBA fatigue practice. This section discusses the following DBA standards and while the reader may decide to focus on a particular code of interest, it is recommended that the opportunity is taken to develop a breadth of understanding (to some extent) of all: PD5500 ASME VIII Div2 ASME III (brief mention) EN13445 Some other fatigue relevant standards and guidance, is also highlighted: BS 7608 BS 7910 In the Codes of Practice / DBA in Action section of the course, attention is...more
