CONCEPT

Contrasting with the leapfrog vorticity and abyssal shoals by moving from hydrodynamic flow to solid-state acoustic resonance. Simulates Gor'kov acoustic radiation trapping and Rayleigh micro-streaming on an orthotropic vibrating plate, where multi-mode harmonic interference forces quartz sediment along bifurcating nodal lines.

LORE

The ash soil stiffens under higher modes; beneath the alluvial silt lies an anisotropic quartz bed that hums at dry integer ratios. 这里的地下水脉暂时凝固为固相共振板,沉积物不再随涡流漂移,而是在克拉尼节线处堆积成冷白色的骨架。When the drive frequency shifts, the branches snap apart and heal elsewhere.

JOURNAL

Stepped away from Navier-Stokes advection to test solid-state acoustic trapping. Implemented Gor'kov acoustic potential $U = 2V_0 [ \langle p^2 angle / (2 ho_0 c^2) - 3 ho_0 \langle v^2 angle / 4 ]$ coupled with secondary Rayleigh streaming drift over an orthotropic stiffness tensor. The bifurcation between $(m,n)=(3,5)$ and $(4,4)$ modes creates distinct sharp spines instead of diffuse shoals. Density variance stayed tight (0.0032) because the nodal lines act as strict attractors, leaving the antinodes nearly swept clean.
