Contents
Modelling self-propelling organisms like bacteria in computer simulations can either be done by modifying the Langevin equation for a passive particle or by explicitly taking into account hydrodynamic interactions of the active particle and the solvent as well as inter-particle hydrodynamics.
In the presentation of this topic both modelling strategies and their underlying theories should be discussed. In addition, a few important results that have been published using those models are expected to be briefly introduced and presented in the larger context.
