    Interactive Wood Fracture
    (The Eurographics Association, 2020) Hädrich, Torsten; Scheffczyk, Jan; Palubicki, Wojciech; Pirk, Sören; Michels, Dominik L.; Michels, Dominik L.
    Abstract We propose a new approach for the simulation of wood as anisotropic material that takes its inherent fiber structure into account. Our approach is based on the Position-based Dynamics framework. We use the Shape Matching approach as the basis for modeling the isotropic attribute of wood. For simulating anisotropic behavior we employ a fiber model based on the Cosserat rod theory. Our approach supports dynamic fracturing and captures typical breaking patterns of wood.

    Efficient Unified Stokes using a Polynomial Reduced Fluid Model
    (The Eurographics Association, 2020) Panuelos, Jonathan; Goldade, Ryan; Batty, Christopher; Michels, Dominik L.
    Unsteady Stokes solvers, coupling stress and pressure forces, are a key component of accurate free surface simulators for highly viscous fluids. Because of the simultaneous application of stress and pressure terms, this creates a much larger system than the standard decoupled approach. We propose a reduced fluid model wherein interior regions are represented with incompressible polynomial vector fields. Sets of standard grid cells are consolidated into super-cells, each of which are modelled using only 26 degrees of freedom. This reduced model retains desirable behaviour of the full Stokes system with smaller computational cost.

    Wind Erosion: Shape Modifications by Interactive Particle-based Erosion and Deposition
    (The Eurographics Association, 2020) Krs, Vojtech; Hädrich, Torsten; Michels, Dominik L.; Deussen, Oliver; Pirk, Sören; Benes, Bedrich; Michels, Dominik L.
    We present a novel user-assisted method for physics-inspired modeling of geomorphological features on polygonal meshes using material erosion and deposition as the driving mechanisms. Polygonal meshes defining an input scene are converted into a volumetric data structure that efficiently tracks the mass and boundary of the resulting morphological changes. We use Smoothed Particle Hydrodynamics to simulate fluids and to track eroded material. Eroded material is converted to material particles and naturally deposits in locations such as sinks and corners. Once deposited, we convert material particles back into the volumetric representation.
