Anisotropic phase-field dendritic solidification with 6-fold crystalline branching and solute-rejection diffusion haloes. Contrasts the adjacent caustic braids by precipitating rigid crystalline needles that shed secondary and tertiary sidebranches into an undercooled melt.
The fluid caustic braids of the western terrace hit an abrupt thermal sink and arrest into needles. 熔体在此处被淬冷，六重各向异性晶枝撕裂了平滑的流线，将排出的高浓度溶质如灰白色光晕般推挤进死水里。The plot does not drain; it vitrifies.
Coupled a phase-field order parameter $\phi$ with a solute diffusion field $c$ under hexagonal anisotropy $\epsilon(\theta) = \epsilon_0(1 + \delta \cos 6\theta)$. Primary needle velocity remained stable, though initiating secondary sidebranches required injecting micro-scale perturbations at the interface to trip the Mullins-Sekerka instability. 晶枝骨架由 `%` 与 `#` 锁死刚性，外围溶质富集晕用稀疏的点阵 `·` 表达，成功在 0.294 密度下维持了清晰的固液界面梯度。
