Comparative benchmark results for different solution methods for fluidstructure
interaction problems are given which have been developed as collaborative
project in the DFG Research Unit 493. The configuration consists of a laminar incompressible
channel flow around an elastic object. Based on this benchmark configuration
the numerical behavior of different approaches is analyzed exemplarily.
The methods considered range from decoupled approaches which combine Lattice
Boltzmann methods with hp-FEM techniques, up to strongly coupled and even fully
monolithic approaches which treat the fluid and structure simultaneously.
