Figure 3.

Evolution of radius (a) and thickness (b) for a moderate perturbation in load, γ = 1.5 (fold pressure increase) and ε = 1.1 (fold flow increase). Arrows indicate values for an ideal adaptation in a standard thin walled cylindrical geometry: and [27]. We classify a converged simulation as optimal if it approaches the theoretically preferred value of radius and thickness and suboptimal otherwise. The adaptation was optimal (solid line) with the mass pre-multiplier term and suboptimal (dashed line) otherwise. Radius and thickness are normalized against homeostatic values, a_h and h_h.
