numerical simulation

Numerical simulation is a technique used to model complex systems and predict their behavior using mathematical equations. By inputting initial conditions and parameters into a computer program, scientists and engineers can simulate real-world processes—like weather patterns, fluid dynamics, or chemical reactions—without physically experimenting on them. This helps in understanding how these systems work, testing hypotheses, and making informed decisions. Essentially, it's like running a virtual experiment that saves time and resources, while allowing for exploration of scenarios that might be difficult or impossible to replicate in reality.
