This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada Resource Abstract In many industries and companies, Modeling and Simulation has been used successfully for important decisions and even some work process changes. However, in many places the use is quite “shallow” and limited to a small number of highly capable and motivated individuals. It has not become “mainstream” outside of few industries such as Automotive, Aerospace and a few others. This is classic case of an innovation being embraced by “early adopters”, but not by the so-called “early majority” and “late majority” (the vast majority of our employees). In the presentation I will show the analogy to other...more
Abstract Analytical modeling and simulation of systems are traditionally done at the component or module levels and usually involve complex 3-D simulations. These types of simulations take a long time to solve but give detailed design direction. In addition, these types of simulations are typically conducted after the project gets into the development life cycle phase. Within a Systems Engineering strategy, modeling and simulation of systems are starting to be done at the product level and usually involve simplified 0-D or 1-D models. These types of simulations run very fast but only give general design direction. In addition, these types of simulations are typically needed during the planning...more

What’s in a Cookie? 6-minute read Sinothile Baloyi - June 30th 2023 Your favourite packaged cookie. What is it, actually? Let’s just focus on the basic ingredients of the kind of cookie you might bake yourself. So, probably wheat flour, sugar, baking powder, maybe chocolate, butter, and flavourings. Now let’s think about the physical properties of each ingredient, the things that your cookie is before it’s a cookie: Flour - powder Sugar- granular Chocolate - colloid composed of cocoa, fat and sometimes sugar Butter – water in oil emulsion Baking powder – compound powder What about your favourite sauce, ketchup, Brown sauce (Yes, rest of the world outside the UK, that’s what it’s...more

Q&A Session Questions 1. What would be the first action organisations should take when considering a strategy for Engineering Simulation? First step is identifying and gathering your Stakeholders and agreeing your Goals for Simulation. Next step is to identify your detail requirements. i.e. What is the ‘to-do’ list you need Simulation to be able to address. 2. What is the most important action organisations should take to improve their Engineering Simulation Capability? Having identified your goals and requirements the most important action is to identify your current position regarding your processes, methods, tools, models etc… Where are the gaps? 3. What are some of the common issues...more
What are the differences between various differencing and meshing schemes? What are the basics of turbulence, heat transfer, and FSI modelling?

Introduction to Practical CFD New Revised Course for 2025 This course offers attendees fundamental knowledge on using CFD in real-life engineering applications. Adopting a straightforward and moderately technical approach, it outlines the CFD process and explains the advantages and challenges of employing CFD analysis in the simulation of complex flow phenomena, as well as...more
Hendrix, Van Halen, Newton and Einstein by The CAE Guy Back in the 1980s, when I was 16 or 17, I was arguing/discussing the “best” rock and roll guitarist off all time with a high school classmate of mine. While I remember it was a heated “debate” where we agreed to disagree: Long story short [1], I was advocating for Eddie Van Halen and he was advocating for Jimi Hendrix. For a little background, my classmate was a guy that seemed, at the time, to be really into rock and roll as he had the look and feel of a head banger [2,3]. I, on the other hand, was, how should I say this … a naïve computer geek and was just coming aware of the larger world around me. Sure, I had been listening to disco...more
Abstract Manufacturing companies look at reliable digital technologies to address increasing product complexity, innovate the engineering design process and reduce investment in physical prototypes. The ability to use simulation and perform design space exploration studies usually remains in the domain of a relatively small group of simulation experts too often isolated from the rest of the organization. Regardless of the adoption of Simulation Process and Data Management (SPDM) systems, there is still a siloed approach to share projects and results. Simulation models are sent by emails or placed on a shared drive with no version control, and disconnected from a common repository with other...more
Simulation and Modelling - State of the Art and Industry Best Practice Thursday February 25th 2016 Museum of Science and Industry Manchester United Kingdom Overview SimBest is an exciting and unique project being funded by Innovate UK to gain insights into the use of simulation/modelling within industry and the current research activities of academics. The work, undertaken jointly by KTN, NAFEMS and GE/Alstom, is now nearing completion. The project has worked with experts who have interviewed senior personnel from over one hundred world-class companies and universities from across the UK. The project findings will be revealed for the first time at this meeting. Background The use of modelling...more
