How to manage uncertainty in CFD: the grid convergence index
CFD simulations are riddled with errors and uncertainties that we have to manage as CFD practitioners. The most commonly used technique to establish trust in our simulations is a grid convergence study, where the so-called grid convergence index is calculated. This value provides us with a measure of the mesh-induced uncertainty and, in many cases, …
