Lattice Boltzmann methods for simulating fluid flow in complex geometries have developed rapidly in recent years. The LB method produces accurate flows and can accommodate a variety of boundary conditions associated with fluid-fluid and fluid-solid interactions. With the advent of large memory/parallel workstations (or Linux clusters), computations on fairly large systems that were considered beyond the reach of even some "super" computers from a decade ago can now be considered routine. We are clearly in a good position to study fluid flow in a variety of microstructures relevant to concrete technology.
