Figure 13:

Schematic of two-dimensional pressure-loaded elastic band adopted from Vadala-Roth et al. [47]. The loading on the band (blue) is driven by fluid forces induced by the pressure gradient between the left and right boundaries of the computational domain. The effective shape of the kernel function changes near the boundary of the computational domain. So we avoid issues that may arise from using a finer structural mesh (MFAC = 0.5) for the two rigid blocks (yellow) by which the top and bottom of the band are fixed in place. In this figure, MFAC = 2 for the band away from the boundary.
