Table 3.
Relative differences (%) in nodal values of mechanical properties (i.e., stress (σ1), strain (ε1), and wall shear stress (τmax)) calculated for each of the one-way–coupled FSI approaches (FSI1-Vxyz, FSI1-Vz, FSI1-Vwom) with respect to the fully coupled FSIf-Vxyz approach. The nodal average of the relative difference of the mechanical properties (X) at each phase (err1t(X)) and err2t(X)) are calculated following Eqs. (3) and (4). Subsequently, the temporal averages of the errors over 40 phases (Merr1 and Merr2) are computed.
