Eulerian Solid-Fluid Coupling

Yun Teng, David I.W. Levin, Theodore Kim We present a new method that achieves a two-way coupling between deformable solids and an incompressible fluid where the underlying geometric representation is entirely Eulerian. Using the recently developed Eulerian Solids approach [Levin … Continue reading

High-Resolution Interaction with Corotational Coarsening Models

Rosell Torres, Alejandro Rodríguez, José Miguel Espadero, Miguel A. Otaduy This paper presents a numerical coarsening method for corotational elasticity, which enables interactive large deformation of high-resolution heterogeneous objects. Our method derives a coarse elastic model from a high-resolution discretization … Continue reading
