was investigated by FEM analysis. Initially, a mesh with respect to the previously computed value) and
convergence study was performed: Figure 6A reports preventing computational power waste. Simulations
the axial force as a function of the number of nodes for were run by imposing the selected displacement with
scaffolds with a different number of layers, indicating an a ramped profile, setting 100 displacement–force data
asymptotic behavior. On this basis, a mesh was selected, points, and obtaining the configuration as displayed
ensuring acceptable accuracy (i.e., <2% variation in Figure 6B.
