Abstract:
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 associated with a height field approach, we
simulation the entire top surface of the water volume with a state of
the art, fully three-dimensional Navier-Stokes free surface
solver. Our philosophy is to use the best available method near the
interface (in the three-dimensional region) and to coarsen the mesh
away from the interface for efficiency. We coarsen with tall, thin
cells (as opposed to octrees or AMR), because they maintain good
resolution horizontally allowing for accurate representation of bottom
topography.
