SUMMARY:Simulation With Contact
DESCRIPTION:Simulation With Contact - Interactive Discussion\n\nAfter the 
 summary presentations, attendees will participate in an interactive discus
 sion. Distributed around the room will be a series of poster boards for au
 thors to gather around with the audience. Authors are invited to bring any
  material related to their paper that could instigate further conver...\n\
 n---------------------\nPrimal-dual Non-smooth Friction for Rigid Body Ani
 mation\n\nOur novel contact solver, based on an primal-dual interior point
  algorithm, efficiently and robustly simulates the non-smooth transition b
 etween static and dynamic friction. Our algorithm is well suited for large
  systems of tightly packed objects with many contacts, which we demonstrat
 e with complex...\n\n\nYi-Lu Chen, Mickaël Ly, and Chris Wojtan (Institute
  of Science and Technology Austria (ISTA))\n---------------------\nPrecond
 itioned Nonlinear Conjugate Gradient Method for Real-time Interior-point H
 yperelasticity\n\nA preconditioned nonlinear conjugate gradient method is 
 proposed for real-time simulation of elastic deformation with incremental 
 potential contact. This method is GPU-parallelizable and demonstrates fast
  convergence. A line search strategy is proposed to determine an appropria
 te step size and achie...\n\n\nXing Shen, Runyuan Cai, Mengxiao Bi, and Ta
 ngjie Lv (Fuxi AI Lab, NetEase Inc)\n---------------------\nA Dynamic Duo 
 of Finite Elements and Material Points\n\nDynamicDuo is a novel framework 
 designed to integrate FEM and MPM seamlessly. The IMEX framework combines 
 the optimal performance of implicit FEM and the flexibility of explicit MP
 M in applying plasticity. We achieve this through asynchronous time-splitt
 ing, where IPC is applied to model inter-domai...\n\n\nXuan Li (University

  of California Los Angeles, Style3D Research)\n---------------------\nCont
 act Detection Between Curved Fibres: High Order Makes a Difference\n\nWhen
  simulating fibre assemblies with standard techniques, we identify spuriou
 s artifacts in the contact forces which are caused by the use of low-order
  proxys for collision detection. We fix this issue by developing an effici
 ent and accurate high-order detection scheme between two smooth curves, wh

 tails-Descoubes (University Grenoble Alpes Inria, CNRS, Grenoble INP, LJK)
 \n---------------------\nGIPC: Fast and stable Gauss-Newton optimization o
 f IPC barrier energy\n\nWe propose a method for rewriting the IPC barrier 
 function using a simplicial-geometric measure of contact. The result is an
  efficient approximation of the Hessian, thanks to our formulation of its 
 analytic eigensystems. These eigensystems further enable an entirely GPU-b
 ased IPC system, resulting i...\n\n\nKemeng Huang, Floyd Chitalu, Huanchen

 --------------\nDifferentiable solver for time-dependent deformation probl
 ems with contact\n\nWe introduce a general differentiable solver for time-
 dependent deformation problems to solve PDE-constrained optimizations. It 
 supports differentiation with respect to all physical parameters involved,
  including shape, material parameters, friction coefficient, and initial c
 onditions. Our analytica...\n\n\nZizhou Huang (New York University); Davi
