The Grid Convergence Index ( ) method requires at least three systematic mesh refinements, each requiring the numerical solution to be in the asymptotic range. When the observed order of accuracy differs from the formal order of accuracy, a lack of numerical precision exists which may result in ...
where u(t) stands for the UH ordinate; indexais the shape parameter that reflects the number of conceptual free water reservoirs; andkis the scale parameter, which is a constant reservoir storage that delineates the average watershed flow time of concentration. Γ(a) is the gamma function ofa...
the reconstructed ΔTGCI is relatively close to the actual ΔTGCI, demonstrating the validity of the reconstruction. To assess the sensitivity of our results to index selection, we compared
the grid convergence index (GCI) was conducted as recommended by Roache [51,52]. Three grids were constructed: A coarse mesh with 1.3 M grid points, a medium mesh with 3.1 M cells, and a fine mesh of 6.3 M grid points. Each numerical solution was completely converged with respect to ...
We performed an O-type structured grid and densification at the bubble injection and trajectory, as seen in Figure 3. A test of mesh independence is carried out, and the information of meshes is provided in Table 3. In the fourth column, the Grid Convergence Index (GCI) proposed by Roache...

To quantify the uncertainty and ensure the reliability of our simulations, we used the Grid Convergence Index (GCI), a method widely recognized for assessing the accuracy of numerical solutions. The GCI provides a measure of the numerical error associated with the grid resolution. When considering ...
Assuming the solutions lie in the asymptotic range, only the first term is taken, which leads to the so-called grid triplet study. Furthermore, according to Xing and Stern (2010), the grid convergence index (GCI), derived by Roache (1998) can be used to estimate uncertainties due to ...
