Pairwise Force SPH Model for Real-Time Multi-Interaction Applications

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 interactions at interfaces is a challenging problem for SPH-based simulations, especially for scenarios involving multiple […]

Modeling and Data-Driven Parameter Estimation for Woven Fabrics

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 experimental protocol for characterizing real fabrics based on commercially available tests. Finally, we create a […]

Inequality Cloth

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 from even an edge-spring-only cloth simulation can be quite severe, noting that the typical remedy […]

Hierarchical Vorticity Skeletons

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 field, which is not possible with any previous filament extraction approach. Once computed, these HVSs […]
