👉 A computational fluid, often referred to simply as a fluid in computational terms, is a continuous medium characterized by properties like density, velocity, and pressure that vary smoothly across space. In computational fluid dynamics (CFD), these properties are modeled mathematically using partial differential equations, such as the Navier-Stokes equations, which describe how the fluid moves and interacts with its environment. CFD simulations aim to predict fluid behavior under various conditions, such as airflow around an aircraft wing or water flow through a pipe, by solving these equations numerically on a computational grid. The computational aspect involves discretizing the fluid domain into manageable elements, applying boundary conditions, and iteratively solving the equations to obtain solutions that represent the fluid's state at each grid point over time.
