Fluctuating Lattice Boltzmann simulations of microswimmers — •Felix Winterhalter, Matthieu Marechal, and Klaus Mecke — Friedrich-Alexander-Universität, Erlangen, Germany

During the last years the interest in microswimmers has steadily increased. To gauge the effect of hydrodynamical interactions between the microswimmers and to include the flow of the solvent around the swimmer, a simulation technique with a good model for the solvent is required. Our method of choice is fluctuating Lattice Boltzmann simulations that includes thermal fluctuations, which are often important for synthetic swimmers. The currently existing particle simulation using the software WaLBerla is expanded to encompass self-propelled microswimmers to study their behavior in a variety of confining geometries and external fields. We are currently looking at ferromagnetic beads in an oscillating magnetic field and the flow field which is developing as a result of the collective motion.
