Ferienakademie 2014 Course 4: Fluid-structure interaction from the nano- to the macroscale

Fluids play a role in many applications from nanofluidic devices to aircraft design. Often one is interested not only the fluid dynamics, but also its interaction with potentially moving, embedded structures. In nanofluidic devices, the fluid is often driven by embedded charged particles, which then can be driven by an external electric field. On the macroscopic scale, understanding the function of a windmill requires both the dynamics of the fluid, in this case air, and the rotating wings. In this course, we will learn about numerical techniques that can be used to simulate such problems.

Topics include:

  • High order immersed boundary and fictitious domain methods
  • High order finite elements
  • Numeric Integration of discontinuous functions
  • Octal tree generators for meshing complex structures
  • Nitsche-Coupling for interface problems
  • Volume-coupled multifield problems (thermoelasticity)
  • Surface-coupled multifield problems (fluid-structure interaction)
  • Macromolecular particle simulation
  • Molecular dynamics and ensembles
  • Force fields
  • Lattice Boltzmann Method
  • Boundary conditions, immersed Boundary Method
  • Relaxation schemes, thermalization
  • Coupling to MD / embedded structures
  • Elektrokinetic equations


Charged point particles driven by an external field through a channel. The particles accelerate the solvent, whose velocity is visualized by arrows.
