A Novel Algorithm for Incompressible Flow Using Only a Coarse Grid Projection
This novel technique for quickly simulating detailed fluids coarsens the Eulerian fluid grid during the pressure solve, allowing for a fast implicit update but still maintaining the resolution obtained with a large grid.
Filament-Based Smoke With Vortex Shedding and Variational Reconnection
Vortex filaments provide an intuitive and compact model for designing smoke effects. This paper introduces a model that includes moving obstacles with vortex shedding, which allows detailed simulations of complex scenarios at interactive rates. The long-term behavior is excellent: energy and momentum stay within reasonable bounds, and computational complexity does not increase over time.
Underwater Cloth Simulation With Fractional Derivatives
This paper introduces the use of fractional differentiation for simulating cloth deformations underwater without the use of a volumetric fluid simulation. The proposed fractional cloth model employs half-derivative visco-elastic elements to model cloth responses to fluid stresses and emulate the memory-laden behavior of particles in a viscous fluid.
Discrete Viscous Threads
This paper develops a model for simulating long, thin strands of viscous materials, like honey poured from a bottle. The model is validated against analytic and experimental results. This same model can be used to simulate elastic rods with implicit solvers, providing a ten-fold speedup over previous explicit formulations.
