Computational domain consisting of a 3 μm × 3 μm × 3 μm cube. A total of 1215 protofibrils (red rods) are randomly placed and orientated in the initial state. Periodic boundary conditions are imposed for all directions. (a) Snapshots of fibrin clot in the steady-state (200 ms after the initial state) and (b) fibrin clot extension in the z-direction. The results are obtained with k^A = 2 × 10⁻³ N m⁻¹ and k^B = 1 × 10⁻¹⁸ J rad⁻².
