Numerical modelling is a method used in various scientific disciplines, including engineering, physics, and earth sciences, to simulate and predict the behavior of complex systems. This approach involves creating mathematical models of the system and then using computational algorithms to solve these models and generate numerical results. Numerical modelling allows researchers to analyze and understand the underlying processes of a system, predict its future behavior under different conditions, and optimize its performance. It is often used to study phenomena that are difficult or impossible to observe directly or experimentally, such as weather patterns, fluid dynamics, and structural mechanics. Overall, numerical modelling is a valuable tool for scientific inquiry and technological development, providing insights and predictions that can inform decision-making and advance our understanding of the natural world.
