Item Boundary Handling and Adaptive Time-stepping for PCISPH(The Eurographics Association, 2010) Ihmsen, Markus; Akinci, Nadir; Gissler, Marc; Teschner, Matthias; Kenny Erleben and Jan Bender and Matthias TeschnerWe present a novel boundary handling scheme for incompressible fluids based on Smoothed Particle Hydrodynamics (SPH). In combination with the predictive-corrective incompressible SPH (PCISPH) method, the boundary handling scheme allows for larger time steps compared to existing solutions. Furthermore, an adaptive time-stepping approach is proposed. The approach automatically estimates appropriate time steps independent of the scenario. Due to its adaptivity, the overall computation time of dynamic scenarios is significantly reduced compared to simulations with constant time steps.
