Numerical modeling is a mathematical technique used to simulate real-world systems and processes. By using algorithms and computational methods, it allows researchers to predict how these systems behave under various conditions. This approach is widely applied in fields such as engineering, climate science, and economics. In numerical modeling, complex equations are solved using computers to create models that represent physical phenomena. These models can help in understanding intricate systems, such as weather patterns or fluid dynamics, and are essential for making informed decisions based on simulated outcomes.
