The major objective of the Research Group is the systematic and
coordinated development and investigation of numerical methods for
the robust and efficient simulation of fluid-structure interaction.
A large number of examples of such problems can be found in various
disciplines. In the field of engineering there can be mentioned,
for instance, civil engineering (bridges, sks scrapers, flexible roofs,
off shore platforms,...), mechanical engineering (valves, pumps,
airfoils, ship propellers,...), process engineering (stirrer, extruders,
injection systems,...) or medicine technique (artificial heart valves,
The realistic transient simulation of such processes is rather
challenging with respect to the numerical techniques and computer
capacities. In addition to the effort resulting form the combination of
structural and fluid mechanical computations the interaction brings in
a variety of complex numerical, informatical and mechanical questions,
which require intensive research efforts to answer them.
This comprises questions of the adequate consideration of the dynamic
and nonlinear interaction itself, the capabilities of partitioned
solution approaches, the appropriateness of established methods from
structural and flow side, the robustness and efficiency of the methods,
the adequate description of complex geometries and its changes or the
topic of a flexible software environment for such problems.
