Volume Conserving Finite Element Simulations of Deformable ModelsGeoffrey Irving, Craig Schroeder, Ronald FedkiwAugust 2007We 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. | |

Efficient Simulation of Large Bodies of Water by Coupling Two and Three Dimensional TechniquesGeoffrey Irving, Eran Guendelman, Frank Losasso, Ronald FedkiwJanuary 2006We present a new method for the efficient simulation of large bodies of water, especially effective when three-dimensional surface effects are important. Similar to a traditional two-dimensional height field approach, most of the water volume is represented by tall cells which are assumed to have linear pressure profiles. In order to avoid the limitations typically ... more Paper (PDF) Additional materials: [movie.avi]Available in the proceedings of SIGGRAPH 2006 |
