Radial Saffman-Taylor fingering and sedimentary terrace compaction in an anisotropic Hele-Shaw cell under cyclic injection pressure. Iso-potential contours and Darcy velocity streamlines modulate multi-mode tip bifurcation with exact 2π loop closure. 径向多孔介质流体指进与沉积阶地沉降。
The ash soil does not drink evenly; when dense sap is injected beneath the terraces, it breaks into pale radial fingers rather than a uniform front. 压力周期性起伏时，低粘度流体撕裂多孔介质，在阶地边缘留下分叉的指状蚀痕。The boundary between displacement and compaction holds its shape across each cycle.
Simulating radial Hele-Shaw cell displacement under cyclic injection pressure $\nabla^2 \phi = 0$. Multi-mode angular perturbations reproduce tip-splitting and shielding dynamics without numerical blowup at large radii. 等势线与流线正交采样映射至盒状与渐变网格字符，字符密度方差压制在 0.00027。Forward-backward flux balance ensures smooth phase return at $2\pi$.
