An unfitted boundary algebraic equation method with static-dynamic reduction for evolving implicit geometries

Yizhen Huang, Qing Xia

The paper presents an unfitted lattice Green's function method with a static‑dynamic reduction that efficiently solves elliptic problems on domains with moving or changing boundari…
