Figure 10. Convergence comparison between SIMPLE and SIMPLEV for different mesh sizes. The vertical axis corresponds to the logarithm of the residual for the momentum and continuity equations. The horizontal axis shows the number of iterations. Top to bottom: (a) convergence history for the backward-facing step problem, 30x30 mesh; (b) convergence history for the backward-facing step problem, 60x60 mesh; (c) and (d) as for (a) and (b) but for the flow past a square cylinder.
