ADD: Analytically Differentiable Dynamics for Multi-Body Systems with Frictional Contact.
TL;DR: A differentiable dynamics solver that is able to handle frictional contact for rigid and deformable objects within a unified framework and enables gradient-based optimization with adaptive trade-offs between simulation accuracy and smoothness of objective function landscapes is presented.

ADD: analytically differentiable dynamics for multi-body systems with frictional contact
TL;DR: In this paper, a differentiable dynamics solver is proposed to handle frictional contact for rigid and deformable objects within a unified framework, through a principled mollification of normal and tangential contact forces.
Journal ArticleDOI
Surface-only liquids
TL;DR: A novel surface-only technique for simulating incompressible, inviscid and uniform-density liquids with surface tension in three dimensions, using an orthogonal projection technique to remove the divergence while requiring the evaluation of only two boundary integrals.
Journal ArticleDOI
Real2Sim: visco-elastic parameter estimation from dynamic motion
TL;DR: The effectiveness of the method for optimizing visco-elastic material parameters of a finite element simulation to best approximate the dynamic motion of real-world soft objects is demonstrated.
Journal ArticleDOI
High-resolution brittle fracture simulation with boundary elements
David Hahn,Chris Wojtan +1 more
TL;DR: Using the boundary element method (BEM) and Lagrangian crack-fronts, a system produces physics-based fracture surfaces with high spatial and temporal resolution, taking spatial variation of material toughness and/or strength into account.
