Sadashige Ishida, Masafumi Yamamoto, Ryoichi Ando, Toshiya Hachisuka Simulating the behavior of soap films and foams is a challenging task. A direct numerical simulation of films and foams via the Navier-Stokes equations is still computationally too expensive. We propose an … Continue reading →

Ming Gao, Andre Pradhana Tampubulon, Chenfanfu Jiang, Eftychios Sifakis We present an adaptive Generalized Interpolation Material Point (GIMP) method for simulating elastoplastic materials. Our approach allows adaptive refining and coarsening of different regions of the material, leading to an efficient MPM … Continue reading →

Richard Jones, Richard Southern In this paper we present a physically-based model for simulating realistic interactions between liquid droplets in an efficient manner. Our particle-based system recreates the coalescence, separation and fragmentation interactions that occur between colliding liquid droplets and … Continue reading →

Sören Pirk, Michał Jarząbek, Torsten Hädrich, Dominik L. Michels, Wojciech Palubicki We present a novel method for the combustion of botanical tree models. Tree models are represented as connected particles for the branching structure and a polygonal surface mesh for … Continue reading →

Hector Barreiro, Ignacio Garcia-Fernandez, Ivan Alduan, Miguel A. Otaduy The simulation of high viscoelasticity poses important computational challenges. One is the difficulty to robustly measure strain and its derivatives in a medium without permanent structure. Another is the high stiffness … Continue reading →

Conformation Constraints for Efficient Viscoelastic Fluid Simulation An Adaptive Generalized Interpolation Material Point Method for Simulating Elastostatic Materials Interactive Wood Combustion for Botanical Tree Models A Hyperbolic Geometric Flow for Evolving Films and Foams A Unified Particle System Framework for … Continue reading →

Tao Yang, Ralph R. Martin, Ming C. Lin, Jian Chang, and Shi-Min Hu In this paper, we present a novel pairwise-force smoothed particle hydrodynamics (PF-SPH) model to enable simulation of various interactions at interfaces in real time. Realistic capture of … Continue reading →

David Clyde, Joseph Teran, Rasmus Tamstorf Accurate estimation of mechanical parameters for simulation of woven fabrics is essential in many fields. To facilitate this we first present a new orthotropic hyperelastic constitutive model for woven fabrics. Next, we design an … Continue reading →

Ning Jin, Wenlong Lu, Zhenglin Geng, Ronald Fedkiw As has been noted and discussed by various authors, numerical simulations of deformable bodies often adversely suffer from so-called “locking” artifacts. We illustrate that the “locking” of out-of-plane bending motion that results … Continue reading →

Sebastian Eberhardt, Steffen Weissmann, Ulrich Pinkall, Nils Thuerey We propose a novel method to extract hierarchies of vortex filaments from given three-dimensional flow velocity fields. We call these collections of filaments Hierarchical Vorticity Skeletons (HVS). They extract multi-scale information from the input velocity … Continue reading →
