Extended Data Fig. 2: Numerical simulation of the BCC models.

a-b, Displacement maps (a) and von Mises stress maps (b) show that the V.1.0 BCC model can achieve venous occlusion during erection. The height and diameter of the flaccid model in the numerical simulation are 9.6 mm and 16 mm, respectively. c, Time‒volume expansion curve, showing that the V.2.0 BCC model exhibits faster erectile deformation than the V.1.0 BCC model.
