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
How is plastic behaviour in metals simulated and used in practical engineering applications? What are potential difficulties and challenges in modelling plasticity problems using FE software? What are the potential errors and limitations of the FE plasticity solutions? This course gives you practical advice with a minimum of theory. Metals Material Modelling: Plasticity The course covers plasticity theories that are widely used to analyse practical engineering applications in metals. Mathematical formulations and equations are intentionally kept to a minimum. Emphasis will be placed on how engineering design incorporates these theories and how the FE method models plasticity. Difficulties encountered...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 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
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

NAFEMS Webinar Series Practical Introduction to CFD Wednesday, 7 September 2011 Overview CFD is a computer-based simulation of predicting what will happen when fluids (gases & liquids) flow. CFD complements experimental and analytical approaches by providing an alternative cost-effective mean of simulating real-life flow problems. CFD has now become a leading research, educational, and design tool. It is being used to better understand physical events and processes and perform numerical experiments. Most importantly, it has now become a design tool by providing capabilities to facilitate design optimisation, reduce design bottlenecks and improve engineering performance, enhance communications,...more
