Aortic bifurcation case. Top: flow rate, pressure, change in radius with time at several locations and pressure gradient between inlet and outlet in the 3-D model (solid lines) and 1-D model (dashed lines) with relative error metrics (Section 2.6). Bottom: velocity magnitude in the reference domain of the 3-D model (colormap). Velocity profiles of the 3-D model (solid lines, axial velocity component) and the 1-D model (dashed lines) at three locations and two time points.
