Tao Yang, Ming C. Lin, Ralph R. Martin, Jian Chang, and Shi-Min Hu The realistic capture of various interactions at interfaces is a challenging problem for SPH-based simulation. Previous works have mainly considered a single type of interaction, while real-world … Continue reading →

Rahul Narain, Matthew Overby, George E. Brown We apply the alternating direction method of multipliers (ADMM) optimization algorithm to implicit time integration of elastic bodies, and show that the resulting method closely relates to the recently proposed projective dynamics algorithm. However, … Continue reading →

Dan Koschier, Crispin Deul, Jan Bender In this paper we propose a novel method to construct hierarchical $hp$-adaptive Signed Distance Fields (SDFs). We discretize the signed distance function of an input mesh using piecewise polynomials on an axis-aligned hexahedral grid. Besides … Continue reading →

Aviv Segall, Orestis Vantzos, Mirela Ben-Chen Hele-Shaw flow describes the slow flow of a viscous liquid between two parallel plates separated by a small gap. In some configurations such a flow generates instabilities known as Saffman-Taylor fingers, which form intricate visual … Continue reading →

Vinicius C. Azevedo, Christopher Batty, Manuel M. Oliveira Fluid animation methods based on Eulerian grids have long struggled to resolve flows involving narrow gaps and thin solid features. Past approaches have artificially inflated or voxelized boundaries, although this sacrifices the … Continue reading →

Xiao Yan, Yun-Tao Jiang, Chen-Feng Li, Ralph R. Martin, and Shi-Min Hu This work extends existing multiphase-fluid SPH frameworks to cover solid phases, including deformable bodies and granular materials. In our extended multiphase SPH framework, the distribution and shapes of … Continue reading →

Camille Schreck, Damien Rohmer, Stefanie Hahmann, Marie-Paule Cani, Shuo Jin, Charlie Wang, Jean-Francois Bloch We present the first method to animate sheets of paper at interactive rates, while automatically generating a plausible set of sharp features when the sheet is … Continue reading →

Albert Chern, Felix Knoppel, Ulrich Pinkall, Peter Schröder, Steffen Weissmann We describe a new approach for the purely Eulerian simulation of incompressible fluids. In it, the fluid state is represented by a ℂ²-valued wave function evolving under the Schrödinger equation … Continue reading →

Morten Bojsen-Hansen, Chris Wojtan When aiming to seamlessly integrate a fluid simulation into a larger scenario (like an open ocean), careful attention must be paid to boundary conditions. In particular, one must implement special “non-reflecting” boundary conditions, which dissipate out-going … Continue reading →
