We develop a new Lagrangian primitive, named Langevin particle, to incorporate turbulent flow details in fluid simulation. A group of the particles are distributed inside the simulation domain based on a turbulence energy model with turbulence viscosity. A particle in … Continue reading →

Cem Yuksel, Texas A&M, 2010: Real-Time Water Waves with Wave Particles

We describe a method for the visual interactive simulation of wires contacting with rigid multibodies. The physical model used is a hybrid combining lumped elements and massless quasistatic representations. The latter is based on a kinematic constraint preserving the total … Continue reading →

We present a fluid simulation method based on Smoothed Particle Hydrodynamics (SPH) in which incompressibility and boundary conditions are enforced using holonomic kinematic constraints on the density. This formulation enables systematic multiphysics integration in which interactions are modeled via similar … Continue reading →

We present a hexahedral finite element method for simulating cuts in deformable bodies using the corotational formulation of strain at high computational efficiency. Key to our approach is a novel embedding of adaptive element refinements and topological changes of the … Continue reading →

A thesis from 2009 that I missed: Barbara Solenthaler, University of Zurich: Incompressible Fluid Simulation and Advanced Surface Handling with SPH

I was recently asked whether there exists any internet forum dedicated to physics-based animation. The two that came to mind are Gamedev’s Math & Physics forum and Bullet’s physics simulation forums (both linked in the right column of the page), … Continue reading →

We present a volumetric iso-geometric finite element analysis based on Catmull-Clark solids. This concept allows one to use the same representation for the modeling, the physical simulation, and the visualization, which optimizes the design process and narrows the gap between … Continue reading →

We present a new hybrid CPU/GPU collision detection technique for rigid and deformable objects based on spatial subdivision. Our approach efficiently exploits the massive computational capabilities of modern CPUs and GPUs commonly found in off-the-shelf computer systems. The algorithm is … Continue reading →
