I have a hard time finding problem sets for validation and
benchmarking of methods and codes for 3d fluid simulation with free
boundaries. Please guide me to (standardized) problem sets or key
litterture that is a suitable starting point. If there are not many
standardized tests I would like to initiate a dsicussion about what a
good test collection should be. I understand that iMechanica is focused
more on solid mechanics than fluid dynamics but the overlap is big.

The best collection I have found so far is the one from SPHERIC (http://wiki.manchester.ac.uk/spheric/index.php/SPHERIC_Home_Page) but there should be more. Meeting the 2D benchmark tests is not a guarantee that a 3D code is working properly

We present an interesting application of ADINA FSI in cardiovascular mechanics, specifically, a potential cause for heart attacks is studied.  Please see

Terence Tao (one of the Fields Medal winners this year) has started blogging. He has a detailed discussion on the Navier-Stokes equations here. It's long but definitely worth reading - particularly because of the wide range of ideas that he talks about.
