Crispin Deul, Tassilo Kugelstadt, Marcel Weiler, Jan Bender In this paper, we present a novel direct solver for the efficient simulation of stiff, inextensible elastic rods within the Position-Based Dynamics (PBD) framework. It is based on the XPBD algorithm, which … Continue reading →

Marcel Weiler, Dan Koschier, Magnus Brand, Jan Bender In this paper, we present a novel physically consistent implicit solver for the simulation of highly viscous fluids using the Smoothed Particle Hydrodynamics (SPH) formalism. Our method is the result of a … Continue reading →

Breannan Smith, Fernando de Goes, Theodore Kim Non-linear hyperelastic energies play a key role in capturing the fleshy appearance of virtual characters. Real-world, volume-preserving biological tissues have Poisson’s ratios near 1/2, but numerical simulation within this regime is notoriously challenging. … Continue reading →

Chuyuan Fu, Qi Guo, Theodore Gast, Chenfanfu Jiang, Joseph Teran Recently the Affine Particle-In-Cell (APIC) Method was proposed by Jiang et al.[2015; 2017b] to improve the accuracy of the transfers in Particle-In-Cell (PIC) [Harlow 1964] techniques by augmenting each particle … Continue reading →

Tao Yang, Jian Chang, Ming C. Lin, Ralph R. Martin, Jian J. Zhang, and Shi-Min Hu 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 … Continue reading →

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 →
