The team worked under time constraints and on a limited budget. Building and testing all kinds of different models of cars is then, of course, not possible. That’s where the supercomputer enters the scene. By simulating the car’s aerodynamics in the computer, you can improve your design before you actually build the model.
The more detailed and realistic your simulation model, the more computing power and memory you need. Jussi Vuopionpera, responsible for operations & sponsorships at the Top Dutch Solar Racing team 2019 and bioinformatics student at the Hanze University of Applied Sciences: “To perform the calculations, we used a hundred CPUs, central processing units, on the supercomputer. As a result, a simulation took only a few hours on average. We couldn’t do such simulations on an ordinary PC because it simply doesn’t have enough memory.”
