WebOne of the most important research topics in the field of SPH methods is the simulation of incompressible fluids. SPlisHSPlasH implements current state-of-the-art pressure solvers (WCSPH, PCISPH, PBF, IISPH, DFSPH, PF) to simulate incompressibility. WebThis work presents a novel, incompressible fluid simulation method based on the Lagrangian Smoothed Particle Hydrodynamics model that clearly outperforms the commonly used weakly compressible SPH (WCSPH) model by more than an order of magnitude while the computations are in good agreement with the WCSPH results. 410 PDF bottom gear memes
