4. FEM vs. Numerical Simulation In the scenario presented in the previous section, the consultants explained the difference between finite element modeling and numerical simulation. The terms “finite element modeling” and “numerical simulation” are essential in the understanding of the role of Simulation Governance. Please watch this 5-minute video addressing the question of why Numerical Simulation is not the same as Finite Element Modeling. Once finished with this video, proceed to the next section which will offer a series of true/false questions to confirm understanding. Quiz What is the Difference Between Finite Element Modeling and Numerical Simulation? This question cannot be answered...more

Mind the Gap 6-minute read Sinothile Baloyi - April 21st 2023 In 1765 James Watt improved Thomas Newcomen’s steam engine, to such an extent that he often gets incorrectly credited with inventing the whole thing himself. How did he do this? Perhaps it was simply serendipity, or could his access at a young age to his father’s shipbuilding workshops - all those hours spent building models of cranes, barrel organs, etc, and becoming intimately acquainted with their mechanics- have given the future inventor the edge? Engineering methods have moved on a lot since then. Now when you hear the word ‘model’ you don’t necessarily picture this: Wooden model of crane, pulley attached. James Watt's...more
Systems Simulation: Far-off Future or Feasible Now? by Chad Jackson, President and Principal Analyst of Lifecycle Insights Move over multi-physics. There's now a different field that qualifies as the bleeding edge of technology in simulation: system simulation. Many organizations are just starting to broach this field in an effort to better understand how systems perform holistically. But what is it? Is it really feasible for practical use today? Let's dive in and discuss. Setting Baselines: Systems Engineering Terminology can be such a challenge. So before we go barreling off to talk about the questions above, let's set some baselines. To start, if you're unfamiliar with systems engineering,...more

This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada Resource Abstract The expansion of the use of simulation across the product lifecycle is critically dependent on full confidence in the veracity of the results of numerical simulations. It’s not sufficient that the results are correct, the process through which the results are obtained to support business or regulatory decisions needs to be transparent, traceable, repeatable and fully documented. Traditional manual documentation methods based on notebooks and shared drives are no longer fit for purpose in a world of simulation data sets of increasing complexity distributed across virtual teams.

The Case for Reckless Engineering 6-minute read Sinothile Baloyi - February 28th 2023 Remember when you were a child and built entire worlds out of just your imagination and some LEGO® bricks, sticks, rocks, or whatever you could lay your hands on? You knew you were building something , but often, at the very beginning, you didn’t know exactly how it was going to turn out. Sure, LEGO bricks often come with instructions for a specific thing, but if you were anything like most kids, you’d build that thing then wreck it all and build something completely made up, and then you’d do it again and again. I once offered my friend’s seven-year-old a boxed LEGO set of a model car, ready to be...more
The Stakes are High; Time to up Your Game Modelling and Simulation of Cyber-physical Systems 5-minute read Sinothile Baloyi - February 22nd 2024 In 2006 Dr Helen Gill, then program manager of the United States National Science Foundation (USNSF) coined the term Cyber-physical Systems . Before that, we had Cybernetics, a term invented by mathematician Norbert Wiener. And before that we had the Greek word kybernan; to steer. So cyber-physical systems are, therefore, systems involving the steering of physical entities of some kind. A lot like you, with your nervous system forever in a feedback loop with the rest of your physiological systems, making endless decisions that translate into...more
