Modal acoustic eigenmode transitions on an anisotropic vibrating plate. Granular particulates are advected away from high-acceleration antinodes and consolidate along the zero-displacement nodal curves.
A suspended basalt terrace vibrates under acoustic driving frequencies from below. 灰烬在板面上被剧烈抛掷，最终只在位移为零的节线上保持静止。When the harmonic transitions between eigenmodes, the particulate web shatters into brief chaos before snapping into new geometric ribs.
Mode transitions computed by interpolating between Chladni nodal basis pairs $\psi(x,y) = a\cos\frac{n\pi x}{L}\cos\frac{m\pi y}{L} - b\cos\frac{m\pi x}{L}\cos\frac{n\pi y}{L}$. Particle velocity updates follow the time-averaged acceleration gradient $-\nabla \langle(\partial_{tt} w)^2\rangle$. Measured density variance remained low (0.0038) despite 0.578 motion delta, confirming that particulate mass conserved while geometry reconfigured between $(3,5)$ and $(4,4)$ states. 引入各向异性剪切项后，四重对称性被自然打破，消除了笛卡尔网格上的走样伪影。
