Subspace Mixed-FEM for Real-Time Heterogeneous Elastodynamics (2405.13730v1)

Published 22 May 2024 in cs.GR

Abstract: We propose a reduced space mixed finite element method (MFEM) built on a Skinning Eigenmode subspace and material-aware cubature scheme. Our solver is well-suited for simulating scenes with large material and geometric heterogeneities in real-time. This mammoth geometry is composed of 98,175 vertices and 531,565 tetrahedral elements and with a heterogenous composition of widely varying materials of muscles ($E= 5\times105$ Pa), joints ($E=1\times105$ Pa), and bone ($E=1\times10{10}$ Pa). The resulting simulation runs at 120 frames per second (FPS).
