Position-Based Nonlinear Gauss-Seidel for Quasistatic Hyperelasticity
Yizhou Chen, Yushan Han, Jingyu Chen +1
Position based dynamics is a powerful technique for simulating a variety of materials. Its primary strength is its robustness when run with limited computational budget. We develop…
A Deep Conjugate Direction Method for Iteratively Solving Linear Systems
Ayano Kaneda, Osman Akar, Jingyu Chen +3
We present a novel deep learning approach to approximate the solution of large, sparse, symmetric, positive-definite linear systems of equations. These systems arise from many prob…
Analytically Integratable Zero-restlength Springs for Capturing Dynamic Modes unrepresented by Quasistatic Neural Networks
Yongxu Jin, Yushan Han, Zhenglin Geng +2
We present a novel paradigm for modeling certain types of dynamic simulation in real-time with the aid of neural networks. In order to significantly reduce the requirements on data…
A Robust Grid-Based Meshing Algorithm for Embedding Self-Intersecting Surfaces
Steven W. Gagniere, Yushan Han, Yizhou Chen +4
The creation of a volumetric mesh representing the interior of an input polygonal mesh is a common requirement in graphics and computational mechanics applications. Most mesh creat…
A Momentum-Conserving Implicit Material Point Method for Surface Energies with Spatial Gradients
Jingyu Chen, Victoria Kala, Alan Marquez-Razon +3
We present a novel Material Point Method (MPM) discretization of surface tension forces that arise from spatially varying surface energies. These variations typically arise from su…
A Hybrid Lagrangian/Eulerian Collocated Advection and Projection Method for Fluid Simulation
Steven W. Gagniere, David A. B. Hyde, Alan Marquez-Razon +5
We present a hybrid particle/grid approach for simulating incompressible fluids on collocated velocity grids. We interchangeably use particle and grid representations of transporte…
An angular momentum conserving Affine-Particle-In-Cell method
Chenfanfu Jiang, Craig Schroeder, Joseph Teran
We present a new technique for transferring momentum and velocity between particles and grid with Particle-In-Cell (PIC) calculations which we call Affine-Particle-In-Cell (APIC).…
