An Efficient Hybrid Incompressible SPH Solver with Interface Handling for Boundary Conditions
Takahashi, Tetsuya; Dobashi, Yoshinori; Nishita, Tomoyuki; Lin, Ming C. (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose a hybrid smoothed particle hydrodynamics solver for efficientlysimulating incompressible fluids using an interface handling method for boundary conditions in the pressure Poisson equation. We blend particle ... -
A Geometrically Consistent Viscous Fluid Solver with Two-Way Fluid-Solid Coupling
Takahashi, Tetsuya; Lin, Ming C. (The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a grid-based fluid solver for simulating viscous materials and their interactions with solid objects. Our method formulates the implicit viscosity integration as a minimization problem with consistently estimated ... -
A Multilevel Active-Set Preconditioner for Box-Constrained Pressure Poisson Solvers
Takahashi, Tetsuya; Batty, Christopher (ACM Association for Computing Machinery, 2023)Efficiently solving large-scale box-constrained convex quadratic programs (QPs) is an important computational challenge in physical simulation.We propose a new multilevel preconditioning scheme based on the active-set ...
