Fig. 3.

Pressure (a,c) and velocity (b,d) versus time and distance in 2 cm increments from the aortic root (x=0, Segment 1) to the end of the left anterior tibial artery (Segment 49), through Segments 2, 14, 18, 27, 28, 35, 37, 39, 41, 42, 44 and 46. The aortic bifurcation is at x=44.4 cm. Pulse waveforms generated using the purely elastic (a,b) and visco-elastic (c,d) formulations in the normal 55-artery model. Continuous pressure and velocity magnitudes are shown using coloured surfaces interpolated from the simulated pulse waveforms every 1 cm. After t=10 s, a zero flow rate was prescribed at the aortic root to show the relaxation of the models.
