Evolution of the interface morphology with time for Vp = 500 μm/s and G = 0.7 K/μm, where the intersection of the contours ϕ = 0 is plotted as the solid-liquid interface with the time interval of Δt/τ0 = 1000, and Λt shows the spacing between the two advancing cells in the degenerate seaweed structures.
