        7What makes 1D simulation different from 2D or 3D simulation and why is it relevant?

        The main difference here is that 2D/3D simulations show the interaction of individual components with their surroundings whereas 1D simulations show the entire design of a system and the interactions of the different components of this system. This makes a 1D simulation excellent for optimising the design of an entire system, while 3D simulation is great for determining the optimum design characteristics of individual components.

        9What are the real-world applications for the tools and techniques that we will learn in this course?

        The existing stringent emission norms all over the world are pushing the automotive industries towards zero emissions. It is becoming very challenging to achieve legislative demands and customer expectations simultaneously. The emission norms have moved from laboratory to real-world called Real Driving Emission (RDE) norms. The simulation tools play an important role in facing these challenges in a cost-effective manner and coming out with optimised design in a short time.
