Simulated bitaxial crystal growth for a initial crack width = \(5\Delta x\) (small crack) and b initial crack width = \(100\Delta x\) (large crack). Progression is shown at representative values of the evolving vein-width (VW). For small cracks, the resulting veins (at \(t=66220\) in a) consist of arrested as well as survivor fibers of different lengths, while large cracks lead to uniform fibrous vein textures (at \(t=59605\) in b)
