SUMMARY:Solid-Fluid Interaction on Particle Flow Maps
DESCRIPTION:Duowen Chen and Zhiqi Li (Georgia Institute of Technology); Ju
 nwei Zhou (Purdue University, University of Michigan); Fan Feng (Dartmouth
  College); Tao Du (Tsinghua University, Shanghai Qi Zhi Institute); and Bo
  Zhu (Georgia Institute of Technology)\n\nWe propose a novel solid-fluid i
 nteraction method for coupling elastic solids with impulse flow maps. Our 
 key idea is to unify the representation of fluid and solid components as p
 article flow maps with different lengths and dynamics. The solid-fluid cou
 pling is enabled by implementing two novel mechanisms: first, we developed
  an impulse-to-velocity transfer mechanism to unify the exchanged physical
  quantities; second, we devised a particle path integral mechanism to accu
 mulate coupling forces along each flow-map trajectory. Our framework integ
 rates these two mechanisms into an Eulerian-Lagrangian impulse fluid simul
 ator to accommodate traditional coupling models, exemplified by the Materi
 al Point Method (MPM) and Immersed Boundary Method (IBM), within a particl
 e flow map framework. We demonstrate the efficacy of our approach by simul
 ating solid-fluid interactions exhibiting strong vortical structures, exem
 plified by various vortex shedding and interaction examples across swimmin
 g, falling, breezing, and combustion.\n\nRegistration Category: Full Acces
