Physics
Avalanche (MPM)
Snow, sand, jelly and water in one material-point solver.
What happens
Four materials in one solver: snow slides down a slope, sand collapses, jelly bounces and water flows, all as clouds of material points. Paint more material with the left button, blast the flow with the right, and switch scenes to see each material fail in its own way.
Equations used in the module
Equations MLS-MPM: particles → grid (mass, momentum) → forces → particles F ← (I + Δt ∇v) F, σ = σ(F) (per material) Coulomb: slide when τ > μ σ_n
