What is CFD simulation?

CFD simulation, or Computational Fluid Dynamics simulation, is a branch of engineering that uses numerical analysis and algorithms to solve and analyze problems involving fluid flows. It allows engineers and scientists to virtually simulate the behavior of liquids and gases in various environments, predicting things like airflow over a car, water movement in pipes, or heat transfer in electronic devices. This technique helps optimize designs, reduce costs, and improve performance without extensive physical prototyping.
