*3.2. Results of FSI Simulation of the Blood Flow*

As a result of solving the problem, the distributions of hemodynamic parameters were obtained from three patients, including blood flow velocity, pressure, wall shear stress, time-averaged wall shear stress, and other parameters. The mechanical properties of the aorta–pulmonary artery–shunt system are shown in Table 5 in the considered computational domain. The most important results from the hemodynamic point of view were obtained at t = 0.09 s, corresponding to the maximum blood flow velocity. Similar results obtained for simple geometry (straight vessel) are presented in Supplementary Materials.

The solid line (1) is the experimental curve, the dashed line (2) is the five-parameter Mooney–Rivlin strain energy density function, and the dotted line (3) is the three-parameter Yeoh strain energy density function. **Figure 5.** Stress–strain diagrams: (**a**) specimen 1, (**b**) specimen 2.
