Contents

This talk introduces the lattice-Boltzmann (LB) method for hydrodynamic flow simulations. We will discuss the physical origins of the method, the numerical implementation, and two different schemes used to couple LB and MD simulations. The first of these coupling schemes is the so-called Duenweg-Ahlrichs type point coupling, the second is the Ladd-type moving boundary scheme. Both of these schemes have been used to model actively propelled particles and a selection of such investigations will be presented.

This talk forms the basis for the followup talk Lattice Boltzmann Modeling of Chemical Swimmers, which is why particular focus lies on the introduction of the LB method.
