Center node: "large scale lattice boltzmann simulations of complex fluids advances through the advent of computational grids"
  Abstract: During the last 2.5 years, the RealityGrid project has allowed us to be one of the few scientific groups involved in the development of computational Grids. Since smoothly working production Grids are not yet available, we have been able to substantially influence the direction of software and Grid deployment within the project. In this paper, we review our results from large-scale three-dimensional lattice Boltzmann simulations performed over the last 2.5 years. We describe how the proactive use of computational steering, and advanced job migration and visualization techniques enabled us to do our scientific work more efficiently. The projects reported on in this paper are studies of complex fluid flows under shear or in porous media, as well as large-scale parameter searches, and studies of the self-organization of liquid cubic mesophases.

Connected through hyperedge HE-1 (induced by source paper "parallel multiphysics simulations of charged particles in microfluidic flows"):

    - "simulation of floating bodies with the lattice boltzmann method"
    - "all good things come in threes three beads learn to swim with lattice boltzmann and a rigid body solver"
