Coupled Problems: Fluid-Structure Interaction

Carat++ can also be used within a coupled analysis of type fluid-structure interaction. What approach is used and how to setup a FSI-computation is explained here.

General Overview

A partitioned approach is used for simulating FSI problems. This means, that for each specific task of the coupled computation a specific program is used. The software envrionment in our case consists of three programms:

  • the FE-code Carat++ for the solution of the structural subproblem,
  • the FV-code OpenFOAM for the solution of the fluid subproblem,
  • the coupling code CoMA responsible for everything else: Simulation control, data transfer, communication, coupling algorithms, ...

A grafical representation fo this setup is given in the following figure:
