...on modelling and simulation. The assignment is to turn a real-world system’s behaviour into a sound mathematical model, implement it in code, and verify that the simulated response matches reality. Here’s what the work involves: first, examine the problem statement I will share and identify the governing equations or empirical relationships. Next, build a computational model—Python with NumPy/SciPy, MATLAB, Simulink, or an equivalent platform all fit the brief, so choose whichever you handle best—and code the simulation so it can sweep through multiple scenarios. Finally, validate the results against the reference data I provide and refine any parameters that drift. Deliverables • Well-commented source code of the complete model. • A concis...
