A linear MARS method for three-dimensional interface tracking
Yunhao Qiu, Qinghai Zhang
For explicit interface tracking in three dimensions, we propose a linear MARS method that (a) represents the interface by a partially ordered set of glued surfaces and approximates…

On Topology of Three-dimensional Continua with Singular Points
Hao Liang, Yunhao Qiu, Yan Tan +1
We propose to model the topology of three-dimensional (3D) continua by Yin sets, regular open semianalytic sets with bounded boundary. Our model differs from manifold-based models…
