What is Computer Simulation? Simple Explanation for Non-Engineers

What simulation engineers are actually doing? It’s been many years since that first spark to become an engineer came to me So… What do engineers do? I now have a very simple answer for that actually (But as usually, simplicity sometimes just hides complexity behind a curtain) « Engineers build stuffs » By stuffs, I mean complex systems. You can argue that people who build simple stuffs like a chair, a pillow or a door are also engineers. Except that their job is less technical and more artistry or skill. If you know how to cut some pieces of wood and fix them together, you can build a chair, not need to know about maths and physics. What kind of complex systems engineers build? The world is huge and almost everything can be seen as a system. Just look around you at the objects you use every day and you will have already some ideas: Your computer Your Car Subway and Public Transports The electric network in your house The electric power plant that supplies the electricity All the domestic appliances you own etc… And those are just the domestic product for your own usage. Now think about what a power plant or a factory would need in terms of systems to work. Because that’s the thing about systems, they can be broken down into sub-systems Think about the components of your computer (The processor, the GPU, etc…)… and how each of them can also be broken down into essential parts that makes them work! Engineers are people who are in charge of understanding how all of those systems work, how to operate them, how to change and improve them, how to design and optimise them, etc… Read more about this on my blog: https://feaforall.com/
