Figure 12.

The instantaneous magnitude of the velocity field for the eighth cardiac cycle of patient 1 under exercise conditions are shown at the mid-aneurysm and suprarenal locations for the 2.2, 8.3, and 31.8-million finite-element meshes at peak systole, mid-deceleration, and mid-diastole. The velocity field changed little between meshes at the suprarenal location, where the TKE was virtually zero, but changed more dramatically at the mid-aneurysm location where TKE was moderate. Mesh independence of the instantaneous velocity fields is not achievable in turbulent regions.
