Title:

    Optimized free surface fluids on adaptive grids with the lattice Boltzmann method

Abstract:


    Capturing all details of an animation with free surface fluids often requires large resolutions for the underlying simulation. In the following we will present an algorithm to speed up the simulation by adaptively coarsening the computational grid. As shown in e.g. [Losasso et al. 2004] for a Navier-Stokes based fluid solver, the speed up of grid adaptivity for fluid simulations can be significant. For the test cases described below, our method results in a speedup factor of up to three.
