Implicit smoothed particle hydrodynamics model for simulating incompressible fluid‐elastic coupling

Fluid simulation has been one of the most critical topics in computer graphics for its capacity to produce visually realistic effects. The intricacy fluid manifests with interacting dynamic elements. coupling such scenarios always challenging manage due numerical instability arising from boundary between different Therefore, we propose an implicit smoothed particle hydrodynamics fluid-elastic approach reduce issue fluid-fluid, fluid-elastic, and elastic-elastic circumstances. By deriving relationship universal pressure field incompressible attribute fluid, apply number density scheme solve Poisson equation both elastic material avoid error multi-material conserve non-penetration condition objects particles. Experiments show that our method can effectively handle multiphase fluids under various physical properties.
