Abstract: | This paper describes an Eulerian approach for partitioned fluid–structure simulations based on a fluid solver using regularly
and adaptively refined Cartesian grids. The particular focus is on the efficient implementation and embedding of the fluid
solver in the context of coupled simulations. Special subjects are the efficient layout of data structures and data access
based on space-filling curves and the realisation of geometry and topology changes. In addition, a coupling environment is
presented that allows for an easy and flexible coupling of flow and structure codes. Simulation results are provided for large
particle movements within the drift ratchet scenario. |
