Volume Conserving Finite Element Simulations of Deformable Models Geoffrey Irving, Craig Schroeder, Ronald Fedkiw August 2007 We propose a numerical method for modeling highly deformable nonlinear incompressible solids that conserves the volume locally near each node in a finite element mesh. Our method works with arbitrary constitutive models, is applicable to both passive and active materials (e.g. muscles), and works with simple tetrahedra without the need for multiple quadrature points ... more Paper (PDF) Available in the proceedings of SIGGRAPH 2007. |
