Fluids in Particular

Summary: We present a constraint-based formulation of a polymeric fluids model, that enables efficient simulation of highly viscous and viscoelastic phenomena, allowing a diverse palette of materials. We have designed a solver that extends PBD to handle efficiently velocity-based constraints. Results range from interactive to large-scale simulations.

Summary: We present a generalization of the Affine Particle-In-Cell (APIC) technique by augmenting each particle with a polynomial local function. This greatly improves energy and vorticity resolution in Particle-In-Cell simulations. The cost of the method is negligible over APIC when using a particular class of polynomial functions.

Summary: We propose an extension to the Generalized Interpolation Material Point Method which preserves partition of unity, non-negativity, and C1 continuity properties. We use this technique to develop an adaptive MPM simulation framework. We also propose a hierarchical transfer algorithm which highly accelerates the efficiency of MPM grid-particle transfers.

Summary: We introduce a unified particle framework which integrates the phase-field method with multi-material simulation to allow modeling of both liquids and solids, as well as phase transitions between them.
