Fig. 6.

Landscape of objective function $\mathcal{J}$ of Neo-fiber ($a=2$) over parameter space. The actual parameters ($C_1=50$ kPa, $C_2=5$ kPa) used in the simulation are shown by a yellow cross and estimated parameters by a red star. Figure on the right shows a “zoom-in” near the estimated values, where a denser grid of parameters was used. 10 $\times$ 10 and 11 $\times$ 14 simulations were performed for the initial and refined parameter sweeps, respectively, with an average computational time of 60.546 s
