Gridconvergence refers to a phenomenon observed in computational fluid dynamics and other simulation-based fields where the solution obtained from a numerical simulation converges to a stable and accurate result as the computational grid, or mesh, is refined. A finer grid means more discrete points or cells are used to represent the physical domain, allowing for a more detailed and precise representation of the underlying physical phenomena.
When a simulation is run with increasingly finer grids, the output, such as velocity, pressure, or temperature
To demonstrate grid convergence, researchers typically perform simulations on a series of grids with progressively smaller
