Modeling Complex Systems with Lattice Boltzmann Methods and Lattice Gas Automata
This minisymposium is sponsored by Canadian Applied and Industrial Mathematics Society/Societe Canadienne de Mathematiques Appliquees et Industrielles
10:30 AM-12:30 PM
Room: Sidney Smith 1087
Modeling complex biological, chemical, and physical systems in the context of spatially heterogeneous mediums and complicated boundary conditions often presents a very challenging task for standard numerical methods. Alternative methods, such as Lattice Gas Automata (LGA) or Lattice Boltzmann Methods (LBM), sometimes are advantageous in large-scale computations needed for studying dynamics of complex systems. The speakers will present basic concepts behind LGA and LBM and review developments and applications. They will demonstrate the power, versatility, and usefulness of these methods by demonstrating some of their applications to complex fluid flows, geophysical problems, self-organization, and biochemical processes.
