Radial Saffman-Taylor viscous fingering propagating through an anisotropic porous sediment matrix. Darcy pressure potential drives iterative harmonic tip-splitting while capillary surface tension arrests micro-scale fingering at the displacement frontier.
The ash soil does not drink evenly; pressure builds beneath the crust until the lighter liquor breaks through the heavier silt. In this sector, radial displacement branches into dendritic fingers before freezing at the capillary threshold. 泥浆在前沿分裂，又在表面张力的勒紧下钝化为坚硬的指状脉络。
Simulating radial Saffman-Taylor instability across an anisotropic porous sediment matrix. Darcy potential drives iterative tip-splitting, while Laplace-Young surface tension acts as a high-pass filter on interface curvature. Without the capillary arrest term, the braille frontier degenerated into high-frequency single-dot noise; regularizing by local edge curvature preserved structural bifurcations at mean density 0.475. 粘性指进与毛细回缩在网格中达成了离散平衡。
