Engineering simulations

Definition

Engineering simulations are computational methods used to replicate real-world engineering scenarios, enabling analysis and optimization of designs before physical prototypes are created. They leverage mathematical models to predict how structures or systems behave under various conditions, helping engineers make informed decisions on design and performance.
