FIGURE 2.

To assess convergence, we perform simulations at approximately three-quarters systole, and we compute the average velocity from time $T=0.5\mathrm{s}$ to time $=3.5\mathrm{s}$. Panel (A) shows the average fluid velocity magnitude across the time interval. Panels (B–E) show slices of the average fluid velocity magnitude for three different grid resolutions. The coarsest grid is shown in light blue, the medium grid is shown in blue, and the finest grid is shown in black. We observe consistent values across all grid resolutions tested
