Engineering Simulation is a computational technique used to model and analyze the behavior of systems and structures under various conditions. By using mathematical models and algorithms, engineers can predict how designs will perform in real-world scenarios without the need for physical prototypes. This helps in identifying potential issues early in the design process. The process involves using specialized software to simulate factors such as stress, heat, fluid flow, and more. Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are common methods within engineering simulation. These tools enable engineers to optimize designs, improve safety, and reduce costs in product development.
