This work presents a post - processing tool for the verification of steady -state fluid flow and heat transfer finite volume computations. It is based both on the generalized Richardson extrapolation and the Grid Convergence Index (GCI). The observed order of accuracy and a error band where the grid independent solution is expected to be contained are estimated. The results corresponding to the following two and three - dimensional steady - state simulations are post - processed : a flow inside a cavity with moving top wall, an axisymmetric turbulent flow through a compressor valve, a premixed methane / air laminar flat flame on a perforated burner, and the heat transfer from an isothermal cylinder enclosed by a square duct. Discussion is carried out about the certainty of the estimators obtained with the post -p rocessing procedure. They have been shown to be useful parameters in order to assess credibility and quality to the reported numerical solutions.
