Eulerian Solid-Fluid Coupling

摘要

We present a new method that achieves a two-way coupling betweenrndeformable solids and an incompressible fluid where the underlyingrngeometric representation is entirely Eulerian. Using thernrecently developed Eulerian Solids approach [Levin et al. 2011],rnwe are able to simulate multiple solids undergoing complex, frictionalrncontact while simultaneously interacting with a fluid. Therncomplexity of the scenarios we are able to simulate surpasses thosernthat we have seen from any previous method. Eulerian Solids havernpreviously been integrated using explicit schemes, but we developrnan implicit scheme that allows large time steps to be taken. The incompressibilityrncondition is satisfied in both the solid and the fluid,rnwhich has the added benefit of simplifying collision handling.
