I am interested in coupling a FE model of a cantilever beam with incompressible Naviers-Stokes solver of openFOAM for the simulation of a flapping fin like structure. Any suggestion will be highly appreciated.
@ Dr. Franco Concli: Thanks for your response. I am working with the benchmark problem HronTurek fsi tutorial in openFOAM. Do you have any good reference for that?
For the coupling, take a look at OpenFOAM's externalCoupled boundary condition (http://www.openfoam.com/version-v3.0+/solution-control.php) and the associated tutorial - the path to which can be found at that link.
if it's still relevant to you, here is a great paper that describes the partitioned approach to FSI:

I have personally found it super useful when trying to reproduce the HronTurek FSI2 benchmark. I have used isogeometric solvers for the incompressible Navier-Stokes equations and the equations of nonlinear elasticity. I wanted to reuse them for the FSI simulation and aimed at the partitioned approach with strong coupling. Among other stuff, the paper above describes how to speed up the convergence of the coupling loop.
If by any chance you are interested in my code, you can get it on GitHub:
