Efficient Simulation of Large Bodies of Water by Coupling Two and Three Dimensional Techniques

Geoffrey Irving, Eran Guendelman, Frank Losasso, Ronald Fedkiw
January 2006

We 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

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
