CFD
CFD (Computational Fluid Dynamics) is a computer-based tool that engineers use to simulate and analyze how liquids and gases flow around objects. Think of it as a virtual wind tunnel where engineers can test how air moves around a car, how water flows through pipes, or how heat spreads in a building - all using computer software instead of physical testing. This saves companies time and money compared to building physical prototypes. It's commonly used in automotive design, aerospace, building design, and manufacturing. Similar tools include FEA (Finite Element Analysis) and CAE (Computer-Aided Engineering).
