CECAM Workshop at the CECAM Node Jülich
Mesoscale Hydrodynamic Simulation of Non-Equilibrium and Driven Soft-Matter Systems
May 09-11, 2011
Forschungszentrum Jülich, Germany
Soft matter is highly sensitive to external fields and exhibits a wide spectrum of nonequilibrium phenomena. This particularly applies to active biological systems, which are able to perform directed motion supported by an internal machinery or external fields. Two aspects are of paramount importance for such systems: On the one hand, they are typical exposed to crowded and hence viscoelastic environments, and, on the other hand, hydrodynamic interactions determine their motion and swarming behavior.
Due to the complexity of such systems, simulations play a particular role in soft matter research. The systems are challenging for conventional simulation techniques because of the disparate time, length, and energy scales, and novel simulation techniques are required to be able to access the relevant scales. Moreover, hydrodynamic interactions have to be taken into account adequately. Considerable effort has been devoted to the development of mesoscale simulation methods such as Dissipative Particle Dynamics (DPD), Lattice-Boltzmann (LB), and Multiparticle Collision Dynamics (MPC) (or Stochastic Rotation Dynamics (SRD)) to resolve the scale problems of soft matter systems. By now, the various methods are well established and are applied to a broad spectrum of problems, with the goal to achieve insight into the mechanisms which lead to the formation of the mesoscopic and hierarchical structures originating from a large number of internal degrees of freedom of the constituents.
The workshop is focused on the behavior of soft matter under non-equilibrium conditions addressing colloids, (bio)polymers, membranes and cells in external fields, e.g., microfluidic channels or capillaries, as well as self-propelled systems. The complex interplay between internal degrees of freedom, hydrodynamic interactions and flows, thermal fluctuations, active motion, and confining geometries generate a wide variety of novel and interesting behaviors and phenomena, but also pose major challenges for theory, simulations, and experiments. The workshop brings together experts from the various fields, who are invited to provide their point of view on challenges in non-equilibrium soft matter research.
